Ai Booster Overclocking ?

Here is a screenshot of CPU-Z Memory tab :

Thanks :)

Mine is at 2.75V, although it largely depends on the RAM modules you have - I've got Corsair XMS.

Your RAM is fine in that screenshot. Is it running at 1T or 2T? Back on the BIOS pics that is the 3rd down - the option for 1T/2T mem timing. If its set to 2T, change it to 1T. Stability test it there and leave it if its OK - gives faster RAM operation if it will work. Won't go into detail - google if you want.
 
Ok , 1T seems to work fine for the RAM.
I tried overclocking with the same specs as you, 250Mhz x 10 , 4x HT, 1.475v v core, 2.75v ddr ram but it wouldn't boot at all and then i tried 1.425v/230x10/4xHT/2.7vddr and it booted but crashed soon after with one of those blue error screens.
Is there a reason why my cpu doesn't seem stable at all over 2.2ghz ?
Thanks :)
 
I think its because your RAM can't handle those speeds, look for a divider setting somewhere and play around with that (FSB:DRAM). I think you will find that should make your CPU frequency go up, while keeping your RAM around 200-220 which it will be stable at.
 
You are reducing the RAM memclock aren't you (3rd pic down)? In the screenshot you did, it was still at the default. The default will give a 1:1 RAM speed : FSB speed - setting this to 230 or more would give a RAM speed of 230 or more - completely impossible for the RAM. Use a divider - go back to one of my other posts.

What temps are you getting on the core / NB etc?

No not change the RAM speed, use a divider so that the change in FSB is not proportinal to the change in RAM frequency, this is because the RAM cannot keep up with the FSB. Since you have value RAM it could probably handle 440mhz, meaning a max FSB of 220 with a 1:1 divider, hence your CPU is not stable over 2.2ghz(220FSB x 10 multiplier). It's the RAM making it unstable. Using a different divider such as 5:4 or 3:2 will help you get over 2.2Ghz.
 
If (3rd pic) (memclock index value / 400) x CPU frequency is any more than about 200-210 decrease the memclock value to the next one down.

In CPUZ, this is displayed as CPU/10 or CPU/11 etc. Decreasing the memclock value will raise this divisor in CPUZ and lower the speed the RAM is running at - hence having it on a divider.

You don't necessarily need to put it to 333, if there is one in between that and 400, that would do until you reach a higher clock (when you will have to drop it further).
 
OMG thank you sooo much ! :) :) :)
This is the first time it has ever even booted using 2.4ghz :)
I think 333mhz is perfect for the RAM, in CPU-Z the RAM speed is 200mhz (400mhz) so hopefully won't have any troubles ! :)
I have PCI-33.3mhz PCI-E-100mhz DDR V-2.75v Vcore-1.475v HT-4X RAM MEM-333mhz
Should i try for 250FSB and not touch anything else ? :P
 
250 FSB will give you RAM a speed of 208mhz (416 DDR) so it should work, 260 will give your RAM a speed of 216mhz (432 DDR). Based on my calculations i think your max booting FSB is 264mhz. Set the FSB to 264mhz and see if it boots, if it does then great you have a 2.64ghz CPU. If not then gradually lower the FSB until it boots. You should get atleast 2.5Ghz out of it.
 
You say that but actually it is superb RAM. People have some amazing clocks out of it.

Try for 2500 and if you get it (you should) good. Personally, I wouldn't want to go any higher than that with mine.
