CPU 7 x 266 = 1.862 Ghz
mem 3 x 266 = 800Mhz
So you want 2.6 Ghz: (you can definitely go higher.)
2600 / 7 = 371
mem max= 800 /371 = 2 multiplier to keep it from going over 800
Set mem to spec timings and voltage
set mem mulitplier to 2
slowly increase FSB to 371 (you might need to increase voltage for stability)
Your memory is only rated for 800 so don't go above 400 FSB without memtesting the memory.
As you increase CPU speed, test for stability. (recommend slowly incrementing)
download prime95 into two directories. run from both places, set one for affinity 0 and the other for affinity 1. Run torture test as on both core as you approach 2.6 Ghz. (make sure Task Manager shows both CPU maxed.) A quick 15 minute run per increment will be good for now.
When you think you have reached your limit for the CPU, run the two prime95 overnight.
Good Luck. (Expect to waste a week of your life on this project.)
Well I dont really know what I'm doing and it keeps shutting down whe I try this stuff everytime I push the save and exit bios button after I do this stuff it shutdowns for like 5 sec the restarts with default and I dont understand why so I just set the overclock function to extreme and let it do its thing in bios and it raised it to 2.01 I guess its better than nothing hopefully someone will get this board and be able to walk me through it step by step
Remember heres what I got
Biostar T-Force P965PT
2x512 DDR2 800 Corsair XMS
Artic Cooler 7 Pro
I will oc to what ever you guys think is safe currently I am at 2.01 and 26c
Maybe you guys can fill in the blanks here is what my bios looks like
well i tried what you said besides for the 2*370 because the only options there are 533/677/800 so I just picked 800. Still just shut down right when I saved and exited bios and reset to default. I dont know what the deal is
well first things first id go google your motherboard and find review sites and see what they got it up to.
next is to read wusy s guide on the forums (real good for beginners)
And the main reason its probably dieing is your taking it too far the guy above said 400 frequency which is mad as first most motehrboards cant do that and 2nd its too big a jump and wont help you at all.
I bet your problem is the memory setting. If those 533/667/800 RAM settings actually correspond to ratios relative to the default 266MHz FSB (1:1/5:4/3:2), then setting it to 800MHz may actually be setting your RAM to 1110MHz.
CPU Voltage: 1.325
FSB Termination Voltage: 1.4 V
(G)MCH Voltage: 1.55 V
Memory Voltage: 2.2 V
System Memory Freq: 533MHz
CPU Clock: 400MHz
PCIE Clock Set: Fixed 100
DRAM Timing Selectable: Manual
CAS Latency Time: 5
DRAM RAS# to CAS# Delay 5
DRAM RAS# Precharge: 5
Precharge delay (tRAS): 18
I just started OC'ing this PC today (I got parts for Christmas :-D ), so I am not sure if it will run stable if I lower any of the voltages. I will probably Test it some more tomorrow. I used wusy's guide to help get to where I am so far.
So far I got Prime95 to run for 30 min with these settings no problem. Hope this helps.
