Space, the final frontier
I've never really had a go at overclocking before and dont plan to kill my PC, however having read plenty of threads with people squeezing some extra performance out of their kit, I fancy a go

This is what I have

E8500 E0 cooled with a Noctua U12P (Akasa 120mm Fan)
P5Q Deluxe - 2001 Bios
4x2GB Hyper-X PC8500 (currently running at PC6400 1.8v)
2x 250GB Samsung Spinpoint Raid 0
HD4870 1GB
HX620
Vista X64

running as it is, using Orthos, both cores hit 40c at full load

Does anyone have this mobo with 8GB and could suggest some settings to try, even if its just to get the memory running at its rated speed?

Thanks
 
Try these. Should be stable.

and what is the VID on the chip? CoreTemp will tell you this.

Hi Gurusan, thanks for the starter, i will try those settings shortly, the vid shown in coretemp is 1.1750v, dont know if thats good or bad?
 
That's a very good VID. I had a 1.175VID chip and it did 4.7ghz game stable at 1.408V and 4.5GHz prime stable at 1.37V
 
hi Gurusan, I tried those settings, but the system didnt post

i couldnt set this to DRAM Frequency: DDR2-900MHz, but it was 901MHz

What do I need to reduce in order to get a result?

Thanks
 
Sorry, try Performance Level should have been 10. Usually when running 1:1 fsb/dram ratio you need this to be at 10.
901mhz is fine
 
hi Gurusan, still doesnt want to post, do you think it's due to having 8GB?

Are we at a lost cause and should just keep it at stock?

Thanks
 
It's got to be the 8GB. It's not a lost cause though.

Try keeping all the settings the same, but change the multiplier to 9.5X and set the FSB to 422
 
ok it now posts, but doesnt boot

has the error "not enough space to copy PCI option ROM [00:1F:02]

Also the dram speed has dropped down to 845mhz
 
Can I chip in with an E8500 overclocking story? I had my E8500 prime stable at 4.5GHz 500x9, both in the cpu only stress test and the cpu+memory test, this was with 1.4V. However, Crysis was the only thing to crash on me. It would freeze, but it wasn't a total pc lock up, I could crtl-alt-del and end the task. I don't think it was the gpu clock as I tried lowering this back to stock and it still did it. I had to drop to 4.05GHz to play the game without any lock ups, but as I say it was fully prime stable at 4.5GHz otherwise. ANy ideas or would this just be another Crysis perculiarality?
 
Here are my current settings with a Q9650, vid=1.25, BIOS 2001, for 4GHz Prime & IntelBurn stable:

I had an E8400, C1 stepping, vid=1.18, in this before the Quad. I had it at 3.6GHz, 400 x 9, 1066 RAM, 1.2v CPU. All other settings the same.

I think you are trying to run before you can walk. Try for 3.8GHz (400 x 9.5) at say 1.25v CPU. If that's stable reduce CPU volts a few steps at a time to find the lowest stable.

You may need to up the NB volts for the Kingston RAM, My reaper is fine at 1.2V.

ok, ive set it to what barkeep suggests and its running at 400x9.5 - 1.2v in the bios, cpu-z showing 1.192v at load using prime95

Now, how do I get the ram to run at PC8500 speeds or am i just going to have to leave it a pc6400?

I left prime running for one hour and the load temp (using coretemp) was 48c on both cores
