Hello.

I was pretty stable at 2.2 GHz ...ran prime 95 for 2 nights...had no errors....then when i tried 10x240=2.4 GHZ....ig ot an error within minutes of unning prime 95....


Now what ive done is raise my voltage from 1.4V to 1.536V (cpuz) and 2.4Ghz is running all good.......have been priming it for like 15 minutes ( i know i gotta do it more but im not getting the FATAL errror which i got within minutes of my last overclock)

SO how long do wait till my next overclcok? HOw much should it be and any other settings i should keep in mind? (CPU voltage, DDR voltage, DDR memory ? current is 266)

What HSF do you have on it? Waiting a few minutes is not even close to a reasonable prime95 run. Do you want be more reasonable? six hours. That's a hefty voltage up, and i hope you're monitoring your temps, and/or have a non-stock fan on it... a 3200+ that needs 1.5+ to run at 2.4 probably isnt the greatest oc candidate unless you're doing something wrong.

Well after reading some review im back at 2.2 Ghz and CPU z tells me i have 1.424V. I( think i am gonna burn in before.....i did burn in for a couple of nights at 2.2Ghz and looked stable.....but ill see it for a ngiht mroe and then may b do a 2.3 Ghz. at the same voltage...see if that works.......


Although im not sure if i should decraease my Dram settings to 266 from my current 333.


Thanks

hi. I overclocked my venice 3200 to 2400 by 240*10 cpu Htt:4x ram:1:1 so it runs at 240 mhz now. ı did not make any voltage changes ı just left them as they were auto for cpu and ram ı mean. Ive been playing games such as most wanted fear doom3 for a week and ı have no problem but ı should mention that ı have a zalman cnps9500 for cooling the cpu. I tried the 250*10 ram:1:1 or other higher cpu frequencies by using ram dividers but it did just not reboot so 2400 is fine ..

cpu idle :34 C load max:41 @2400

Hey....


So can you check your voltage usuing CPU-Z (google it) and post it back. I know its auto but then i wanna know exactly what it is.

Also HOw did u setup ur RAM as 1:1. I have a A8n-SLI motherboard ...where can i find the ram ration on that?
January 24, 2006 10:50:14 AM

I am at work now but as far as ı remember it is generally about 1,375 -1.412 you know it changes all the time. ı have an epox mainboard. ıf you set your ram settings auto it will be same with your cpu frequency but if you slow down to 166 than your ram divider will be 6/5 and if you set it to 133 mhz then your divider will be 3/2 ok? meanwhile what about your rams? what is their brand?

Simple: go as far as you can, then back off. My Winchester 3000+ was SuperPi stable for a day at 2.4 (9*266), so with the safety net I'm currently running (260*9). There's no sense in going to the bleeding edge and dealing with issues..

Re: taking it to 266-- only if you're using DDR333 sticks. Using 240*10 will actually run DDR400 under spec with the 333 divider, so it's not being stressed at all. You might squeeze tighter timings, actually.

i have a OCZ premier series PC 3200 DDR400. copper plated. 2.5 3 3 7.

SO now ive been priming the cpu at 2.25......225x10 at auto voltage.

If i wanna overclock it to 2.4 GHz......should i wait and prime it more....then mayb go 230x 10 ...prime more ...then 235.....and then 240?

If the system become sunstable anytime...increase my voltage...my RAM is on 266 right now at 2.25.

Tell me im right? :roll:

my friend don't be afraid it doesn't get hurt that easily try increasing the fsb with the ram first ı mean try the fsb of ram same with the cpu if something goes wrong it just doesn't reboot and goes to default settings automotically or just doesn't boot the windows or it freezes while playing a game then you understand you went so far.. ın my opinion you don't need to run prime96 for hours just try some heavy games such as fear for an hour or two it gives you a signal . ı have a cheaper ram (kingston value 3-3-3-8 and it works fine at 240 mhz(ddr 480)same fsb with the cpu. If something goes wrong then you can try lowering the fsb of your rams such as 266 but you should try to set the fsb as high as you can first then stop increasing the ram and focus on the cpu. ı had a 2600 barton stock clock was 1916 but it worked fine for 1.5 year as 2172mhz with a vantec aeroflow and it did not die ı sold it. so don't give up easily
January 24, 2006 5:52:15 PM

OHH.......so "ıf you set your ram settings auto it will be same with your cpu frequency"

that means it will be 1:1......see i gotta try that now.

im gonna try 2.4Ghz 240x10....at auto memory ....with auto voltage lets see if that works....(at skool right now :p )

If im succesfful at 2.4 GHZ......and i have to use a voltage of 1.475 to 1.5 is that ok? Or do i even need that much?
January 24, 2006 5:57:55 PM

ı will just tell you what ı have done: I haven't touched any single voltage settings ı just left them as they were (default bios setting) auto for most of them ı just changed the http multiplier because you know you shouldn't exceed 1000 ı changed it from auto to 4x (4*240:960) and it works all fine now ı m on the net for an hour and my vcore changes from 1.360 to 375 but after playing some games it raises 1.410 maximum my vdimm is 2.756 chipset 1.616 agp 1.536

cpu temp: 33 system temp: 29

but ı should mention that it is snowy outside...:) 
January 24, 2006 10:44:41 PM

K now i pushed it to 2.28 GHz 228x10. auto cpu V.....auto memory Mhz.

Running prime 95 to see if its stable or not.....ill be updating on this overclock.

I SET THE MEMORY TO AUTO >>......that alright? considering that at auto the fsb/ram ratio should be 1:1?


THanks and wish me luck :p  :p

I Finally OCed My System Even Higher (Look Below At My Specs) How Much Higher Do You Guys Bet I Can Go? 8)
January 25, 2006 12:09:13 AM

im very unorthodox with my ocing. i crank it up to the max bootable freq. then i prime for an hour. if thats good, i run 3dmark 05 and 06, ususally if they pass im satisfied. if not i add voltages, if that fails i lower the freq.

and why is your mem so low clocked? use 333. if ur not exceeding 250htt. and also, your 3200 should hit 2.8-3ghz on air
January 25, 2006 12:26:12 AM

?... My RAM Is Running At 500MHz Speeds, What Does That Hafta Do With 333?
January 25, 2006 6:05:39 AM

ıf you set it auto, yes it will be same with the fsb of your cpu. the logic of dividers are so simple let me explain a little bit. when you set it to 166 mhz(ddr 333) it means that 166 = :6/5 ratio if you set it 133 mhz (ddr266) then the ratio is 133 = 3:2 examples:
cpu fsb=240*10:2400
ram ddr auto:=240

cpu fsb=240*10:2400
ram:D dr 333=240*5/6=200

cpu fsb= 300*9=2700
ram :D dr 266=300*2/3=200

got it? it is all in your hands try it to the limits.
and don't forget not to go higher than 1000 (htt)
January 25, 2006 9:43:14 AM

Yeah, I Already Understand All That, But Its Noted, Appreciated
January 25, 2006 7:06:20 PM

SO i was increasing the fsb in 10Mhz increments from 2.25Ghz (super pi 32M passed) to 2.27(super pi 32Mpassed) ....then..2.29, 2.32, 2.34, and then 2.36 (at 2.36 GHZ although it passed the 32M i thought it was good place to stop for th ngiht and i let it on prime 95 but after 5 hours and 40 minutes of priming there was THAT hardware error) My voltage was at 1.424V (auto).....whast the problem here?
January 25, 2006 7:20:47 PM

Try Uppung The Voltage About 1/2 Volts Or So...
January 25, 2006 8:39:22 PM

0.5 VOLTS>>.. :o 


that makes it from 1.424 to 1.9V


O well i increased it from 1.424 to 1.472 ...is that alrite?
January 25, 2006 11:15:08 PM

Yeah Thats Good (But You May Hafta Go Higher, Nah Man .5 Volts Is Half A Volt
January 25, 2006 11:49:17 PM

K now i got someone to do the overclock for me...


Basically what he did was.

change some thing to 1T from 2T in the memory settings...left ddr at 333....also increased the ddr V to 2.8 ....FSB to 240 (240x10). The cpu volateg is at 1.472V.

considering i did enough priming (about 2 nights at 2.25 Ghz) at prime 95 without any errors.......thsi overclock is working fine....

Have had no halts in games opr anything. Might keep it at 2.4 for a while. :D

When I Get My Tax Check Im Upgrading To A Dual-Core Opteron 170 And A This Liquid Cooling Kit Converted To Run On A CPU Instead Of A GPU, Im Gonna Replace The Water Coolant With Mineral Oil.......... http://www.xoxide.com/thermaltake-tide-water-cl-w0052.h...

Then Im Gonna Try For 2.8 - 3.0GHz
January 26, 2006 12:29:28 PM

how did u manage to get close to 1000HTT @ 2.6ghz? :? i got a 3200+ venice oc to 2.5ghz with 250*10, 1:1, 4xHTT*250=1000. my question is how do i up it to like 2.6,2.7 or 2.8 without exceeding the 1000HTT? and what if its lower than 1000htt assuming around 800~900? does it affects overall performance and stability? anyone? :roll:
January 26, 2006 1:04:31 PM

you should lower your htt multiplier from 4x to 3 or 2 x according to your fsb for example if you set 300*9 then you should lower your htt to 3x from the bios
January 26, 2006 1:10:11 PM

I have a Venice core I've taxed to the max. Right now its at 245*11 = 2695 and it is rock solid. I had to start a month ago at 2600 @ 1.525 Volts to be stable and I slowly increase it over time. I have Folding@Home running in background so that im at 100% load 24/7. The basic bios settings are 245*11 on FSB*Mutli, HTT is 245*4, and Ram in on 1:1. My ram is Mushkin Redline DDR500 2Gb (1Gbx2) on 2t timings. I couldn't get 1T stable.

I should also mention my rig is water cooled. The pump cools the two 7800GTX's in Sli then my proc next and I still cant get the proc above 100 F under load lol.

There is an Excellent overclocking guide on DFI-street.com Use search parameters "Definitive AMD overclocking guide". Its a long thread but very very helpful to noobs and intel converts (me :p ).

OC'ing my system successfully took all day and the tweaks happen weekly. You have to have a good cooling system, whether it be HSF or WC, stock just won't do if you want the most out of your processor.

My advice is be patient and dont increase voltage until you have to and monitor your temps like a hawk. You've voided your warranty by OC'ing (obviously) so we wouldn't want you to burn your proc up and have to pay for another one.

Edit: For clarification, my voltage now is at 1.532. After upping to beyond 1.625 I got very little extra headroom from the insane voltage so i backed it off to 1.532 which is where I hold it at now.

Lower the HT multiplier further. Running HT under spec seems to make little difference, the gains in performance resulting from the higher CPU clock are orders of magnitude higher.
January 26, 2006 1:58:24 PM

thanks for the tips guys... so your saying that i can run @ 900~980HTT without noticing any loss in performance? my ram is CORSAIR TWINX2048-4000PT XMS 2GB (2 x 1GB) DDR500 can up it till 290fsb and my cooling is quite adequate.. :D  @ 2.5ghz my idle is @ 34~38c and load 41~44c.

Nothing noticeable. I used (much) lower HT speeds in trying to sidestep the Neo4-F 219 bug... it only made a major difference if you go to extremes, like using a 1x HT 'multiplier' ;)

The best analogy i've heard about the HTT is that it is like having a 12 lane freeway with only 8 cars on it, each in their own lane. Opening more lanes (overclocking) will not improve performance because each car already had its own lane.

I try and keep mine between 900-1100, it just depends on how the multiplier falls. Also, 41 isnt bad, its a tad warm but then you think about Intel CPUs running around 55-60 and then you realize AMD is pretty spiffy :) 
January 26, 2006 2:41:55 PM

thank you.. i'll go try it now. :)

my Prescott 3.0Ghz overclocked to 3.48Ghz runs at 47C under full load. Take the cover off, and it runs much cooler. :)

Hye...

I ahve my amd 64 venice 3200+ oced to 2.4 Ghz. and the cooler i have is CNPS Zalman 7000BAluCU.

ON average as in idle its like 35-37 and on load climbs to 45-46 like when runnin folding@home?

That normal? for a zalman....

AND ye FOR HOW LONG DOD U RUN YOUR FOLDING@HOME BEFORE U OCED IT TO WATEVER U HAEV RIGHT NOW?

Specification and stock settings:

S939 Venice 3200+
200 bus x 10 (clock-limited) = 2GHz
Model: F
Stepping: 2
Revision: DH-E6
Core Voltage: 1.40v
Cooler: Stock w/ thermal pad

RAM: 2xPC3200@DDR333 (1 stick is faulty @ PC3200)
Motherboard: Abit NF-95
PSU: No-name 400w.

I really like this CPU. I managed to go from 2.0 to 2.55GHz (1.45v Vcore) or just over, the only limiting factors being the motherboard's lack of overlocking features as well as unmatched PC3200 memory that fails at PC3200 speeds.


Methodology

Despite the rubbish memory I was able to achieve a 25%+ overclock, in a very short space of time. I used the bios, and two Windows two apps: ClockGen (to raise bus), and CrystalCPUID (to adjust Vcore and multiplier).

To get 2.5GHz using an Abit NF-95 Motherboard:

1) Make sure you disabled Cool-n-Quiet in the BIOS and in Windows.
1) Enter BIOS. Set RAM speed to PC 2100/DDR266 (you can go higher if you have better RAM).
2) Set HT Link: CPU<>NB multiplier to x4
3) Load Windows. Run CrystalCPUID, raise vCore to 1.45v and set multiplier to x9.0
4) Run ClockGen and raise bus speed in small increments to 280MHx

285MHz x 9.0 = 2.56GHz
HT = 1140MHz*
RAM = 283MHz

* Try and keep the HT speed close to 1100MHz (max) for stability.

That's it. There are quicker, easier ways to overclock this little gem and there's a good chance it'll give you around the same or even higher than what I was able to achieve. I have not seen one single Venice fail @ 2.4GHz.

Relatively old, but still gold

I paid peanuts for the motherboard (Abit NF-95), and the system has been cool as well as rock-solid for two years. Neither is it noisy or requires any case cooling. It handles everything from business tasks to video transcoding, and I don't have to worry about it overheating even under full load. I see a lot of these CPU's being sold for very little money, the same for the boards they run on..most people want dual-core or HD chipsets, but for most tasks this older combo is more than enough with plenty to spare.

The only areas I would like to emphasise are the fact that the stock cooler comes with a thermal pad, and I would also recommending getting the best memory you can not so much for the performance, but for the stability.

Notes

The A64 doesn't benefit that much from stressing your RAM past PC3200 speeds, the same bus and HT speeds. Also, the memory dividors are set internally by the CPU (based on its default core speed), not by your motherboard's chipset. Hence a 3200+ and 3500+ will each use a different dividor in order to run your memory at PC200 speeds (/10 and /11 respectively).

Nice 3 year old bump lol.
