Problem with my new P4 3.4 CPU (maybe?)

[Al_P4]

Hi all, im new to the forum

Ive had my system 3 years now and its run perfectly, its never blue screened, locked up or crashed. My system is as follows:-

P4 2.4(533Fsb)/coolermaster aero fan
Abit IC7-G M/B
1.5gb Kingston PC3200 (2x512/2x256)
120gig Seagate IDE HDD
Winfast A310 Geforce FX5600 256mb
Samsung 16x DVD-RW
Jeantech tower/350w PSU/3xcase fans

I bought a P4 3.4 Prescott from ebay and I fitted it last night. The system has been stable. Its ran alot hotter than my 2.4 but thats to be expected.
Since ive bought it off Ebay ive been worried about it being faulty. The seller has stated he will happily replace it within 30 days and has even offered to help with RMA replacement direct to Intel after the 30 days is up. The cpu was sold as "brand new" and does look brand new.

I ran it on Hot CPU Pro 4 and it flagged up the L2 cache as being a problem. It wouldnt even run it through any of the L2 tests. I then put my 2.4 through the test and it went through fine.
Im not sure if Hot CPU supports my chip or not and I just dont know if this chip is faulty. If anyone has any ideas, can help in any way let me know.

Regards,

Al

What are you running your memory at, both with the 2.4 in as well as the new 3.4? One thing I would try is drop down to just the two 512 sticks in the dual channel configuration and see if that makes a difference. Sometimes mixing memory size can cause issues, particularly at faster memory speeds.

I'm not familiar with that test software, but you might try another test to see if the 3.4 seems stable with something like Prime95.

...Also, how hot is "alot hotter"? If the 3.4 is getting up to the 70's under load then you need more cooling. You didn't reuse a stock Intel 2.4 cooler on that Prescott did you?

OOps... I see you have a Coolermaster...

The 3.4 runs at up 68''C while under load (running games) etc, the 2.4 never used to run above 55''C under load. My coolermaster Aero is rated to 3.6GHz so should be fine.

All the memory modules in the PC are kingston DDR400 and of the same type. They are not dual channel though. I have kept them at the default values in the bios and not altered any of the latencies etc.

Ive run the test again, this time with 1x stick of 256 and it still fails on L2 cache.

How good is this Prime95? does it seriously cain a system enough to show up any hidden faults?

Ive downloaded Prime95 and Metabench, going to see if they throw any errors up.

Prime95 is a very good test of processor stability... Overclockers have used it for a long time to see how far they can push it.

I would think if you have something wrong with your L2, it will show up as errors in Prime95. If you can run the torture test for a day without errors, I would think the chip is OK.

Never heard of problems in L2 cache, usually if some L2 is faulty, they rebag them ads celron or just throw them out...

Have'nt heard of this benchmark either... usually if a Pc is Prime95 stable for 24h+ and it runs memtest86 for a few hours, you have nothing to worry about...
