After my problems in my previous post with a Multiplier of 8 I decided to have a go with 377*[email protected] 1.45v, temps between 44/42c on the cores under load.

Running Prime95 Blend currently hopefully I should get a nice over nighter.

I'm a little concerned about my memory clocks though

Standard OCZ Gold 4GB is 800MHZ @ 5-5-5-12

With the above overclock my Ram is running 754MHZ 4-4-4-12..... will this make my ram slower or faster than stock? - I dont really want to loose any speed in it?;)
 
Slower. I have the same problem with mine. I have had the damn thing stuck on 3.2ghz (8x400) for the past week as it did'nt want to budge any further. Today i thought, to hell with it and went back into the bios and fiddled around. I actually got it to boot at 3.4ghz (378x9) with 1.4v vcore. It has been running prime small fft's now for four hours and appears to be stable with temps being 31/33/32/31 under prime. Tomorrow if this proves stable, i will go for 3.6ghz (9x400) which should get the memory back up to stock.

Thing is, these quads need the bandwith to get the best out of them so if it is'nt stable at 3.6ghz i will have to use the 2.50 multiplier for the memory and drop the timings to 5-5-5-12 and have it running at 945mhz. Mine is good for at least 974mhz.

So with a ratio of 1:1 and tighter timings surely the loss of ram mhz cannot course it to run slower or am I wrong?

With an intel rig you would almost always benefit from higher memory speed rather than tighter timings. However, you might want to test this for yourself with everest for instance :) . You're only running 50 mhz below stock so you'll never notice the difference anyhow...
 
O.k so I just tested with everest, they're just numbers to me so can some-one tell me the conclusion to this, to me it looks as though the slower MHZ clock is quicker?

Ram@4-4-4-12 754MHZ - [email protected] :
Memory Read-7222 MB/s
Memory Write-2900 MB/s
Latancy-62.6 ns

Ram@4-4-4-12 800MHZ - [email protected]
Memory Read-6339 MB/s
Memory Write-2493 MB/s
Latancy-73.4 ns
 
You obviously can't test at different FSB and CPU speed, that would yield wrong results. Just stick with your cpu at 3,4 and be happy with it :) . You may also want to try with a different ratio, say 10:8. Your ram would then run at about 470 MHz. Once again you could test with Everest, but remember that the results will only say something about the memory performance if CPU and FSB speed is the same. There is also a FSB to northbridge strap setting in BIOS which you could try and fiddle with (if you've got that option in bios)

What car is that in your sig? :p

Drrr of course brain ache kicking in!!

O.k will stick with it, just dont like the idea of things underclocked when your trying to overclock!!! :confused:

Its an XJR ;)
