Aspire 7720G Upgrade

Hi people! Recently I had a little upgrade adventure of my Aspire 7720G, replaced the nV 8400M GS with 9600M GT 512MB, added 4GB DDR2 @ 667MHz, and then I decided to upgrade the CPU also. I was thinking about T9500 for a long time, then I came across Intel's X9000 CPU (OEM, not the ES). I installed it, BIOS recognized it, Windows also (Win 7 Ultimate x64), but then I noticed something strange. It works only at 1.2GHz, in idle and in 100% load, when it should be at 2.8GHz. I tried my luck with power schemes, I have the latest BIOS, updated drivers and no change at all. CPU-Z reports it works at 1.2GHz all the time with a multiplier x6, it should be at x14. RMClock didn't help me at all, CPUgenie also. Old CPU was T7300, it was also working at 1.2GHz with multiplier x6 in idle but in 100% load the multiplier jumped to x10 and it worked at full speed; 2GHz. Windows Experience Index with T7300 was 5.1, for X9000 is 3.9!!! What could be the problem? Is there a way to fix this? Any ideas?

 

try using crystalcpuid to change the multi, you should be able to set it to what ever you want.

 

It's a bit of an overkill, but have you tried to reinstall your OS? Or just make a temporary dual-boot, in order to check out if it's OS related or it's BIOS related.

 

Still no progress, it looks like my multiplier is locked at x6, everything else is marked with X, I can change it to x14 like it should be but nothing happens, still at 1.2GHz. How can multiplier on Extreme CPU be locked?

 

I tried WinXP Pro SP3 yesterday, the same thing, shows up at 1.2GHz, I even tried flashing to old BIOS version, no change, now I'm back at the latest version

 

OK, here are the things I tried. OS re-install, clean XP Pro SP3, after that Win 7 Ultimate x64, both show 1.2GHz, so I would say this isn't OS related. Tried CPUgenie, RMClock and CrystalCPUID, all report the same with maximum multiplier at x6. So now I'm thinking the only thing that can cause this is BIOS, but since I have the latest one there is no help is there. I never heard of anything like this but can this be a faulty CPU?

 

Definitely BIOS related in my book Sorry, you have one last shot though, you can ask someone to modify your BIOS. I had a few links and I'll post them... if I find them in first place (a little crowded with bookmarks)

 

Thanks man, that would be awesome! I'll just wait here
