3800+ overclocking, where to now?

[zcomuto]

I'm using a 3800+ with stock cooling. Default clock speed is 200*12 for 2.4GHz

I've overclocked to 2.606GHz now and it seems stable at 11 * 237

Any higher, and i'm experiencing some crashing, although it passes a SuperPI calculation and Prime95 Benchmark.

WHere to from here? Have i reached a limit, or will changing voltage(or anything else) do anything? All I have changed is the multiplier and FSB.

Thanks again.

Overclockin is mostly about the memory,give us some specs on your computer.Votages timings etc.

changing voltage will increase stability but contributes to extra heat. also remember to set pci/agp bus to 33/66mhz or your oc will be a disaster. lower ht multiplier to 3 when going above 300fsb and set the ram divider 1 level lower than stock setting so that memory wont be a factor in overclocking. What is left is your motherboard, cpu, and powersupply. lol u dont oc a psu but a good quality one is recommended. Depending on your mobo, your oc could differ since some mobos crap out well before the 300 mark. To increase stability just raise vcore by small incriments everytime the system becomes unstable or crashes and retest. good luck

I have a M2N32-SLI Deluxe. (Do you want a complete CPUZ report?) and my PSU is a 600W FSP Epsilon.

And th extra heat, how much, and how much is a safe amount? my CPU is at 52C right now.

 

[illicitsc]

i assume thats the msi, cheapest am2 board out there. naw i dont need the cpuz. 52c is the max you want. 60c is nono even though it's within thermal guidelines. you may want consider a better hsf. also test your overclocks for 12-24 hours with prime 95 or folding @ home to ensure stability. ocing is long and tedious but pays off in the end (there is always a luck factor in the end)

First off if you have the N4-32 chip.....it makes the whole system slower as it trys to run at 2 X's 16 by cutting bandwith in half.

Sorry if this is not your MB chipset as I do not know the MB your talking about and in too much pain to google it.
Off to the back Doctor I go right now.

Heat appears to be your enemy.Is the side panel off of case?
This site will help.

Nice tool,once you have found your max,on htt,cpu and memory.

My chipset is the nVidia C51XE.

And i'm about to try what illicitsc said. I have Speedfan and Everest to moniter tempratures.


Can i keep Prime95 running in the background whilst doing other things?

Ok...i can't find any of that in my BIOS. What does it appear as/under?

 

[illicitsc]

ram configs are found in cpu configuration if u have and award bios that is. the cpu clock settings / vcore/ vdimm /agp/pci buses are located in the jumper free settings

 

[zcomuto]

i'm being stupid here. I still can't find the RAM divider.

Dont i need to set it to 1:1 or something?

 

[illicitsc]

er sure, since you are on ddr2, im used to 939 but ya 1:1 should work fine since its down clocking your ram to ddr400

 

[zcomuto]

Oh - is setting the divider 1 below stock setting it to DDR533? (Rather than DDR667)

 

[illicitsc]

yes

Actually, this is the mobo he has:
http://www.asus.com/products4.aspx?l1=3&l2=101&l3=300&model=1163&modelmenu=1
And I'm sorry to tell you, it's not a MSI, and it's not the cheapest either. It's one of the few mobos that has the nForce 590 SLI top-of-the-line chipset.

Maybe you should reconsider your position about CPU-Z

 

[illicitsc]

lol M .. Msi, bad guess on my part, naw still dont need the cpuz. he can post screenies when he is ready to brag. 3ghz comon baby! o btw does that mobo have built in wifi?

 

[jonathanm]

i dont know about his, but ive just bought the same mobo, an asus m2n32-sli deluxe and this came with wifi built in. However it did say on it that there is the option to not get the wifi attached and have 2 extra usb ports instead.

 

[zcomuto]

also remember to set pci/agp bus to 33/66mhz or your oc will be a disaster.

I've set PICe_1 to 100MHz (I beleive that means PCI bus is 33MHz?)

Will i need to change the other one as well? (THere is nto a gfx card in it)



My temps are around 52C idle and 61C under load. I'm thinking that is too high. Have i reached a (safe) limit with the current heatsink?

 

[illicitsc]

NO the pcie is not the pci bus.
keep the pcie at 100mhz
find your agp/pci lock !!!!! or use clock gen and oc and see if the pci bus moves. if it doesnt then its auto locked, if it does move dont oc until u can find the lock. ocing the pci bus makes your comp very unstable

 

[zcomuto]

using CLockgen, everclocking does not increase the PCIe or PCI busses.

 

[illicitsc]

then your pci bus is auto locked which is a good thing
