Hey peeps this might be a bit of a noob question lol but i have looked all over to try and find a easy tutorial sorta on how to do this and not had much luck.

I want to overclock my pc without damaging it :p I have played with the settings a bit & overclocked my CPU & RAM but im not sure how far i can go or if what i have done is right. Heres the images of my specs from everest.

Its just the ram settings that baffle me and i dont wanna play about with them all and fry my memory lol.

Any advice would be appreciated.

Cheers Guys. :)
 
If you can hit 3.1ghz at the moment id try 3.2ghz (400x8) which allso means your ram will sit nice at 800mhz if you select the correct mem divider.
As far as ram settings go all left stock will be fine if it runs at the moment stable at 830mhz.
 
@lanzarobbie - I have just left my voltages at stock as i didnt wanna play with them and blow my pc up haha.

@TheMrWibble - it seems stable at those settings i have now. I managed to get it to 3.4Ghz but it wasnt stable (rebooted randomly after loading the OS)

I havent tried with a lower multiplier yet. I might try that later on today.

Cheers :)
 
Sorry to hijack the thread but i just upgraded from a E2200 to a q6600 on a asus p5kc.
I have it running at 8 x 400
coretemp vid = 1.32v
bios reading 1.3v
cpu-z reading 1.28v
which test do i use and for how long in prime 95 to make sure its stable ?.
Thanks
 
hitman000, you missed the inclusion of the CPU-z [Memory] tab but Memset covers this info . . .

This 4GB Geil Black Dragon DDR2 800Mhz kit you have . . . was it sold as DDR2-800 4-4-4-12 timings or 5-5-5-18 timings? . . . the [SPD] info seems to indicate its the latter? (JEDEC #3) . . . if thats the case it may help to "slacken" the timings manually to 5-5-5-18 . . . you can find this info out by looking at the label attached to the memory or perhaps your shop receipt

Also, as your running the memory on a [5:6] memory-multiplier your overclocking it past its rated speed (400MHz >> 420MHz), to slow down the frequency your only choice would be to a) reduce the FSB or b) change the memory ratio from [5:6] to [1:1] sync, this means the the RAM will run at the same speed as the FSB i.e 350MHz-FSB will equal 350MHz memory speed (DDR2-700) . . . using the [1:1] memory-setting will in theory allow you to overclock your motherboard up to 400MHz-FSB without overclocking the ram! :cool:
 
When i put my rig together it was all set to auto in the bios, and the ram said it was running @ 5-5-5-18 but on the sticker it says CL=4-4-4-12 so i changed them because i thought the board was running them wrong lol. Im not sure what i change regarding the memory multiplier. :confused:

Cheers
 
Ok i have been looking thru my settings etc and i have managed to suss it out. I am now at 1:1, 425mhz x8, Stock voltage.

Going to start benching soon and see what i can get and if its stable or not. Im just a little worried about killing my machine lol.

Are everest scores any good? My score looks pretty decent below.

That's a good start :) Go for 400x9 at around 1.45v if your temps are okay.

Cheers for the reply :). I went to do the WEI assesment on win7 and my pc BSOD'd code 0x00000124 could that be that my voltages arent high enough. I ran prime 95 for like 10 mins and temps didnt go past 43c

If i tried 400 x 9 @ 1.45v that would overclock my ram too much ? atm im back at 400 x 8 stock volts.

Also windows is reporting my clock speed wrong 3.2Ghz (bios) = 3.6Ghz (win) & 3.4Ghz (bios) = 3.8Ghz (win)
 
400x8 stock volts will probably not work, most needed a voltage boost past 3.0.

Give it a couple of notches of voltage in the BIOS and make sure you pass P95 Small FFTs for a couple of hours (I had my i7 crash 6 hours in, but 2 should do for now). Make sure you have the dividers set so that your RAM shows at running at 800mhz and make sure you have the timings and RAM volts per the spec on the RAM (you often get a sticker on the side with timings/voltage).

400x9 would be exactly the same stress on the RAM as 400x8.

Note you may need also a couple of notches of Northbridge voltage for 400fsb to be stable. Make sure the NB doesn't get too hot - you may have to point a fan at it as most are passive and cook under stress
 
Hey m8 cheers for the reply. The weird thing is im not sure where i should go from here because windows & cpuz are showing 2 different cpu speeds by 400mhz difference. Its stable now @ 3.2ghz in cpuz & 3.6ghz windows :S, cpuz makes sense 400x8 = 3200. I just dont see why windows has all of a sudden stopped reading the clock properly lol.

My ram sticker reads: DDR2-800 4-4-4-12 - 2.0V but when i first built my rig the ram was running @ 5-5-5-18 (all default auto settings) so i just changed them to the ones on the sticker not playing with volts or anything.

Im not even sure if im doing this right lol. The whole memory thing confuses me.

Cheers :)

Windows XP will read the cpu speed wrong, its probably estimating highest multiplier of the cpu not the actual. You need to set the RAM to 2-2.1v really as i've had these Blackdragon kits and they don't OC that well, default in the BIOS might be like 1.85V, which might be fine for CAS 5 400MHz, but CAS 4 might not be stable at that volts.
 
Windows read the original multiplier only and the actual FSB combination. If you reduce the multiplier, windows will ignore that. However, if you OC your system using original multiplier and just upping the FSB, it will reflect exactly the speed as stated in your bios and CPUID. That's what I noticed with mine. Could be wrong though.
