LGA775 Core2Duo, Core2Quad OVERCLOCKING guide

[Dabombinable]

the highest i've had it is 577mhz, but i don't know think my Q6950 can go that high with the 9x multi. 

Sweet. Combined with my case and a ghetto AMD stock fan (from an FX 8350 cooler). I might add my 80mm case fan too.

yeah. you have to remember that my nb was on 1.36v and has a fully copper heatsink with 2 heatpipes cooling it as well. the exact fan i normally use is a Foxconn PV902512LBSF 2A

Only 1.36V? My P5Q Turbo's NB was able to handle 1.44V easily due to the cooler I installed. The P5Q Deluxe has NB cooling issues?

no, thats just the highest i have need to go. my ram or cpu is probably the issue and i might be able to go over 600mhz if they were was better.

I need 1.38V to get the FSB to 470MHz with my Xeon.

your nb mustn't be as good as mine then. silicon lottery.

Hi guys new to overclocking. But have a few questions that I want to ask.

 

Current Specs:

 

Gigabyte EP45-UD3P 

Intel Q9550 (Currently OC to 3.4ghz with 400mhz fsb, running stable @ 45~C)

2x2G Cosair DDR2 @800mhz (5 5 5 18)

2x2G Patriot DDR2 @800mhz (4 4 4 12)

Asus GTX560

 

So currently I am OC to the stable 3.4ghz, but now I want to at least get 3.8ghz. My question is would I be able to get to the 3.8ghz range with my current setup? Because I kind of maxed out the 1:1 ratio with the 800mhz ram I have. What would I need to do inorder for me to go higher? Also, is running 2 sets of ram with different timings bad?

 

 

Thanks for the help

Is your RAM an 800MHz kit? If so going to 3.8GHz will take your RAM to ~900MHz, which is may or may not do. Best way to find out is try, if your board supports saving of OC profiles do that so you can quickly swap back, then bump the FSB to around 450 for a ~3.8GHz clock.

 

And if you've not been having issues I don't think it's bad- but I won't claim to be a RAM expert. You may find running them both at 5-5-5-15 allows you to get 900MHz from them for the 3.8GHz clock.

Does the RAM have heatspreaders? If so there is a high chance that it can do 1066MHz  at anywhere between 2-2.2V, though you will need to relax the timings a bit (6-6-6-14 should be fine, if not then 7-7-7-15).

[Dabombinable]

BTW, does anyone know the maximum voltage a Pentium 4 630 (Prescott) and Pentium 4 631 (Cedar Mill) can handle without degrading?

All of the volts!

 

~1.6-1.65

 

Just go to town on it.

I don't want to have the CPU's quit while I'm benching (my P4 630 which hasn't even been overclocked more than twice might be degraded after my first noob no tutorial overclock-1.9V and the FSB at 300. Don't ask me how, but my P5K-VM handled it, the cooler not so much-fan bearing seized from the heat).

Hi, yup it is 800mhz.

The patriot is 2.1v looks like this

And the corsair is 1.8v looks like this

http://images.highspeedbackbone.net/skuimages/large/C13-6134_chiclet01_ea_mn_4517034.jpg

Right now, all the voltages are set to "Normal". So you are saying, save the current profile then just bump the fsb to 450mhz and changing the timing from 5 5 5 18 to 5 5 5 15? And then monitor the temps, if it unstable then change the voltages?

Thanks

run them at 2.1v on 5-5-5-18 and they should be ok. try 425 fsb first, them if that works, try 450. if you go straight to 450 it you might find it is too much of a big jump and the ram or cpu or northbridge might need a bit more voltage.

[woosahh]

I tried 425 fsb and everything worked fine, did the stress test on prime95 max temp was aound 68-70 degrees.

Then i bumped it to 450fsb and it wouldnt boot.

So i bumped the

Vcore 1.2375 -> 1.3v

Cpu term. 1.2 -> 1.3

MCH core 1.1 -> 1.3

Dram voltage 1.8 -> 2.1

And everything else normal. Then i booted up and it worked, did prime95 test, says errors and then computer frozed. Maybe i need to bump vcore up a bit more?

Well this sucks, after 4 hours of assembling my OC rig with my p5q deluxe, I discover that I didn't do the socket mod correctly. Now to undo all of that work to fix it. On the plus side, I can still run a suicide overclock on my second e6500k.

try somewhere between 425 and 450 go up in small steps like 5-10fsb at a time to see where it crashes. also if you can get it to bsod, i can tell you what is causing it to crash which might help decide which voltage needs increasing

4 hours? did you put it in a case and do all the cable management?

Try a mid point between 425 and 450, at 70c you're running up to the 24/7 limit for temperatures so I wouldn't go too far with the voltage.

It takes me about 10 minutes to set up my overclocking bench, watercooling included. Do you put it all in a case or something?

Yep, I even managed to get the IDE cable for my RAID 0 array looking neat. And I get better NB and VRM temps in the case due to the fan setup. BTW, I'm about to start my run of suicide clocks with the second E6500k, using cinebench 2003, R11.5 and R15.

indeed. i just dump everything on my test bench which is a gigabyte z97 soc box

Hi, so i set all the voltages back to normal with only dram voltage 2.1. Then bumped the fsb from 425 to 435.

It booted, but when i did prime95 test core #0 and #1 would have hardware failure detected while core 2 and 3 are fine.

a bit more cpu voltage ~0.025v

Hello, still have hardware failure in prime95

I have vcore @ 1.24375v

Mch core @ 1.3v

Dram voltage @ 2.1

Also, i set pci express frequency to 100mhz or should i leave it auto?

Thanks

leave the pcie at auto. is the mch core the nb or fsb voltage? try 1.32v on that and vcore@ ~1.26
