How are you getting on now? 4Ghz yet? :D

Not so good :(...

tried to bump it up to 433 (3.90ghz) blue screen, physical memory dump.

I think it's my ram. As it said 866mhz when it only supports 800mhz. Tried to look at the system memory multiplyer and lowest it would do is 2.00! Unless I'm looking in the wrong place??
 
It will be the ram. Strange one that as the bios i used had loads of multipliers. I think it may be because you have the timings set to SPD as the memory frequency is blued out too. Set your memory timings to manual and set them to 5-5-5-18 for the first four. Just leave the rest as they are. Hopefully you will be able to select a new multiplier and frequency now.

Nope :mad:...

the only options are from 2.00 upto 4.00 ....
 
Bugger. Looks like we are stuck for the moment then. That's the thing with these 1333mhz fsb cpu's. 6400 ram is'nt really quick enough for them as you will soon run out of headroom when clocking. You could try increasing the ram voltage and slackening off the timings to see if you can get it stable but it's quite a compromise. Personally, for now i would get stable at 3.6-3.7Ghz, i would expect your ram to be able to do 824 mhz as that's only a small increase. At that speed i would also tweak the voltages to see how low i could get them before losing stability. It's up to you then if you want to get faster ram to get this up to 4Ghz. This stuff is very good by the way. The board should be good for around 470mhz on the fsb according to several reviews.

Yer i've read around that above 3.6ghz has a minimal performance gain on gaming. But I will look at updating my 4gb ram to a faster set in the future! Thanks for all your help :)
 
just to give a last reply.

Here is a screenshot of the lowest voltage and highest cpu speed I can do:

The ram really is a killer, won't load windows unless it's dead on 800mhz :mad:... I will look into getting a better set within the next 6 months and hopefully be able to clock this bad boy to 4ghz!!!
 
Nice low volts for 3.6Ghz. Looks like you got a good cpu there. It might very well go beyond 4Ghz. I would ditch that ram asap. That Gskill PC2 8500 is only £35 for the 2Gb kit. I would buy that and stick yours on the bay. You should get £40 or so for a 4Gb kit.

Is there a lot of difference between 2 and 4?
