Overclocking AMD 5000+ BE to 3.2 Ghz

[omnimodis78]

Greetings!

I need to overclock my 5000+ BE to 3.2Ghz. Currently, it's at 3.02 - which was easy to get to given that only the multiplier had to be touched, but getting above this is a bit more complicated (for me). I can get it there -to 3.2- but it's not stable at all under load. I've been trying to get as much info as possible, and i'm not dumb in such matters, but honestly I cannot understand half the stuff being talked about in regards to timings, increase this and that, etc. My specs are Biostar TF570SLI (up-to-date BIOS), 2+1Gb OCZ DDR2 Platinum Edition (rev.2), 2x8800GT OC, Western Digital SATA 500gb, 750w psu. Good air-cooling. Any help would be greatly appreciated! Really!!!!

Ciao!

Assuming your temps are good, have you tried a little more voltage? The key word being "little"

What HSF do you have?

First and foremost, if you are just trying to hit a 16x Multiplier to get to 3.2ghz, cpu temps and voltage numbers going to have the biggest affect and thus, we would need to know what heatsink and fan you are using as the poster above said. For other overclocking options, I'm
wondering more about how your HT and memory settings are. It sounds like you're running two mismatched sticks of Ram, a 1gb one and a 2gb. Please provide their rated speeds and timings.

Hey - I can boot into windows at 3.2 when setting the core voltage to 1.425 (one step lower at 1.400 and it can't even boot into windows). Without any stress, the machine is stable - but it reboots after c. 10 minutes of gaming or 2 minutes of stress test (with everest) - and at 100% cpu load the temp is around 58C. HSF is Zalman CNPS8700 NT ( http://zalman.com/ENG/product/Product_Read.asp?idx=278 ). Just to note, the case is pretty well ventilated. But it's all aircooled.

wow you have my exact system escept i have 9800gt's, more drives and the zalman 9500.

 

[teh_boxzor]

have you treid loosening timings and messing with the cpu clock?

 

[omnimodis78]

Shabodah - thanks. I'm running identical sticks of ram. I'm using these: http://www.newegg.com/Product/Product.aspx?Item=N82E16820227139 . As far as the the HT and memory settings are concerned, I have not adjusted them - I left them at the default settings.

What does "loosening timings" mean?

 

[shabodah]

Well, from your data, it sounds like you are hitting your processor's ceiling, but, there is no good way to find out exactly where that is without messing with your HT and multiplier settings. To start this process, I'd recommend attempting to run your computer at 12x250 with the memory set for 667 divisor. If things are happy there, then you can work you're way up towards 3.2ghz. My personal 5000+ BE processor will not run stable beyond 3.18ghz (12x265). I can get it to boot into windows, and run most applications, but when it hits 100% on both cores, it starts to error out. The processor is still running pretty cool and I've tried all sorts of voltage adjustments, but the cpu just stops at 3.18ghz. Recently, I've run into the same issue with the new 6000+ processor which runs stock at 3.1ghz at 15.5x200. It will run fine up to 3.36ghz, but nothing I do matters beyond that. These numbers are pretty typical give or take 100mhz for these processors.

What does "loosening timings" mean?

If you're not changing your HT or Multi at all, the timings for the RAM would not have any effect on what is going on.

RAM timings are one of the most complicated things to deal with when overclocking. I'd recommend you read some articles on it before messing with them much. But, to loosen them means to set their numbers numerically higher as timings are faster the lower they are numerically.

I think that Tom's got luck and had a great chip when they did the 5000black review. Most people are not getting 3.2 at all. Most top out around 3.0...

I guess I'm one of the fortunate ones. Mine is running rock steady @3.2 1.4v. I have a Sycthe Katana 2 cooler and I think the temps are okay but have never been able to get a decent temp. reading off it. It seems to have the Brisbane thermal sensor bug.

 

[omnimodis78]

Hmm i was rather sure that getting to 3.2ghz wouldn't be such a major issue - i mean, of course, it would require some tweaking, but I think i got the right temps at 3.2 currently, i just need to get it stable under stress. This is my problem, i don't know what to start tweaking... I would love to get a reference point and then go from there. If i hit the roof with the processor, then i will accept that, as long as i know that i have tried everything at my disposal, and right now, I know there is much more to try before admitting defeat hehe. Plz keep the suggestions/ideas/comments rolling!

 

[omnimodis78]

I would love to upload a screenshot of everest to show you guys the specs while it's running at 3.2ghz, but i have no idea how to do that.

 

[shabodah]

You did disable Cool & Quiet, right?

 

[teh_boxzor]

omnimodis hit the prntscrn button on top of the home keys and paste it into an image editing software and save...ill try to do mine right now.

 

[omnimodis78]

hey guys - thanks for all the feedback so far! Yes, i have C&Q disabled. If i could only upload the printscreen of everest running its stress test i could show you the settings i'm at while running at 3.2ghz. The issue is that i know it's not going to remain stable when i start playing games - MAN i really want to run stable at 3.2ghz!!! Shabodah.....we have the same cpu and mobo dude! fantastic investments if you ask me... What setting are you at in bios to get 3.2 stable???

 

[omnimodis78]

**correction** - sorry Shabodah....i meant to write teh_boxzor's specs are similar to mine - no offence meant in case you have something better!

 

[teh_boxzor]

i used multi at 15 and 213 frequency volted at 1.425

 

[omnimodis78]

Thanks teh_boxzor! Using your numbers appears to have been successful! My machine has been running at 3.2ghz with the memory clock at 399.6mhz. Rock solid performance during games, stress test, etc. Great stuff! Thanks to all for your feedback!

 

[teh_boxzor]

NP mate. glas to help!

 

[keyter]

I got the same too!!!

AMD 5600+ BE + CM Hyper TX2
BioStar TF570Sli
OCZ Reaper DDR2 1066 2 x 1G
Sapphire HD4870 1G
Corsair TX650 PSU

CPUz shows my memory to run at 350Mhz. I manually set the timings from 5-5-5-15 to 4-4-4-12 1T, but the frequency remains at 350. The divider is auto set at /7 as my CPU multi is currently at 12 (I think) and my FSB at 234. Will it be wortwhile to get the memory up to 400mhz by lowering the CPU multi further and raising the FSB, to get a better divider?
I also have an aftermarket NB cooler, Thermalright HR05 Sli. Its quite close to my HOT 4870 1G, but cooling should be sorted.

My Bios allows the multiplier up to 15X only. Should I use some 3rd party software to raise the Multi beyond this?

When I use the Auto Overclock System in BIOS, I get a rock steady 3.05Ghz, but the voltage sets to 1.55 or such, which I feel is a bit high.

 

[teh_boxzor]

just increase multi to 15 and cpu frequency to 213 like i said memory should run 400 mhz...

I got mine to 3.118GHz with no problems. Close enough for me! Check out my specs.
