OC dedicated folding quad

Postby uncle fuzzy » Sat Dec 22, 2007 12:19 am

I just built a quad folder on the cheap, and would like to squeeze the max out of it.

Q6600 G0 (whatever the hell G0 means, CoreTemp says I have that one)
mobo- EVGA e-7150/630i GPU mobo (save on video card)
RAM- 2GB G.Skill PC2-6400/800MHz
Stock cooler

I have it folding it's first WU at 2.6GHz with an FSB boost and no other changes. I'd like suggestions on what to do to it tomorrow morning between WUs. At 2.6 GHz, Core Temp has all 4 cores at 42C. I'd like to crank it with no more parts to buy (at this time). It helps that it's in an unheated room. I have no idea what any of the RAM tweaks mean that I've seen here, so if you think I should do some of that, please be very specific about what I have to do.

Thanks in advance for any suggestions.

edit- XP Home SP2, Win SMP

edit- per the rules, I'll keep a record of the current settings here, updating as we go.

1- 288X9, 2.6GHz, 44C, P2653 @ 11:10/frame, 2269.61 PPD, RAM 5-4-4-14
2- 311X9, 2.8GHz, 48C, P2653 @ 10:31/frame, 2409.89 PPD, no RAM adjustment
3- Tried 322/2.9GHz and RAM 4-4-4-12, many problems, back to #2 settings
4- 322X9/2.9GHz, memory ratio 1:1, recent change, no frame rate or temp, yet
5- crashed and burned, won't POST, can't get to bios to do anything, looking at a slightly higher class of parts
6- RMAing the mobo. I'll post the new hardware when I get it. Merry bleeping Christmas to all.

Starting over with a new mobo- GA-P35-DS3P Rev. 2.0, X1950Pro, everything else still the same.
7- 333X9, 3.0GHz, 56C, P2653 @ 9:08/frame, 2774.89 PPD, these were the settings it booted with
8- 350X9, 3.15GHz, 57C, P2653 @ 8:51/frame, 2863.73 PPD
9- 356X9, 3.2GHz, 58C, P2653 @ 8:41/frame, 2918.69 PPD
10- 367X9, 3.3Ghz, 59C, P2653 @ 8:26/frame, 3005.22 PPD
11- 378X9, 3.4GHz, 60C, P2653 @ 8:12/frame, 3090.73 PPD
12- 389X9, 3.5GHz, 60C, P2653 @ 7:58/frame, 3181.26 PPD
13- 400X9, 3.6GHz, 58C, P2653 @ 7:49/frame, 3249.23
14- #13 EUEd, back to #12 settings
15- installed higher cfm rear fan and dropped core temp 4C

I would increase the fsb and till you reach 50c temps. Probably 3.0ghz.
Do not go over 400 fsb it screws up the proformace.

The Go is good it means it made to overclock.

Stock FSB on this mobo was 1066. I'm at around 11-something right now. Multiplier is from 6X to 9X. This is all from memory, I'll look the bios over better between WUs.

edit- Current first step setting is 288X9 for 2.6GHz (according to CoreTemp). No voltage or RAM adjustments (because I don't know what to do with them). Next step around 0600 EST.

That is true of the Intel 965 chipsets. I didn't know the AMD chipsets had the same strappings as Intel... ?

When you're in a spending mood again -- a cheap video card. Integrated video theoretically ties up bandwidth that can be used by the CPU, but the CPU to RAM pipe may not be your bottleneck.
AMD Athlon X2 Dual Core 4200+ (2.2 GHz)

The video is set for 64MB of shared RAM, the monitor is on a 5 minute timer, and I only use it to check the client every 3-4 hours. If needed, I think a new cooler would come before a video card- depends on how the OC goes.

OK, the current settings are at the bottom of the OP per uncle_fungus's rules (uncle_fungi?). (It's 311X9/2.8GHz)

Next question- RAM settings. I stole 2X1GB out of my other SMP machine. It's G.SKILL F2-6400PHU2-2GBHZ, labeled as 4-4-4-12. According to my bios, it's running at 5-4-4-14.

Do I change the settings? Just set the numbers in bios to match the label? I hope the bios works that way. Does the SMP need more than 1GB? This is a dedicated folder, while the other on isn't (and only has 1GB now). I started by giving the quad anything it might want.

You can keep pushing you CPU until it reaches 70-75 °C :mrgreen:

Run stresscpu v2 for stability testings.

If you computer crashes (blue screen or reset), rises the cpu voltage a bit.

Here are the steps I got (voltage are bios settings, not real values ... 0.1V Vdrop) :

3.2 GHz at 1.35V
3.4 GHz at 1.45V (or 1.475V on one of my machines)
next values ar from water cooled machine (to reach these values, you also need a PSU that is capable of delivering more than 20A on the 12V line powering the CPU)
3.6 GHz 1.55V
3.9 GHz at 1.65V

These are just informative values ... always keep the temperature below 75°C, that's the main rule.

Depends, does your BIOS allow raising the VDIMM voltage to the 2.0-2.1 volts that your memory requires to run at 4-4-4-12 timings?

http://www.gskill.com/en/f2-6400phu2-hz.html

If you can't raise VDIMM your better off with the less aggressive settings your running now.

Memory timings are not very important on Core 2 machines ... it won't change performances much :(

The bios VDIMM range is 2.0-2.2 so I tried bumping the settings again.

#1- Tried 322X9/2.9GHz and set memory to 4-4-4-12 @ 2.1v. This gave me a POST error message to reset CPU and/or memory frequency.
#2- 322X9/2.9GHz, default memory at 5-4-4-14 and let bios set voltage. Same error message.
#3- 316X9/2.85GHz, default memory settings. Machine started. Loaded it down and walked away. Checked it 5 minutes later, and it had crashed.
#4- Back to 311X9/2.8GHz and running fine.

Is this where the computer is telling me to give the CPU a little more voltage? CoreTemp says it's at 1.25, but bios says 1.275.

Dis you set your memory ratio to 1:1 :?: (you need to run your memory at the same speed as the FSB)

Now you lost me. How do I do this? Everything in the bios is at default settings except the cpu frquency.

I don't know your motherboard (and the manual provided on the website doesn't detail the BIOS configuration) :(

This option should be called "Memory frequency ratio" or something like that. (it should be located to the same location as the other frenquency settings (PCIe, FSB, ...) or in your memory settings (with the timings)

P.S : don't forget to fix your PCIe frequency too, to 100 MHz ;)
