Windows 7: BSOD for 2 Months

Small FFT's test CPU cache and very little memory.
Large FFT's access' a lot of memory - but in-place option keeps it limited
Blend is not run in-place, so it cycles the tests through a lot of RAM

All tests stress the CPU
In-place large FFT's and Blend also test CPU/RAM interface (mobo in all but Athlon64)
In-place large FFT's stress CPU more than Blend
MemTest is better at testing RAM

You have fast crashes in Blend - and not so fast in In-place large FFT's. The difference here is the amount of memory tested. I'd suggest running MemTest overnight just to be sure.
If it's not RAM, then the other forms of memory will be tested by the stress tests that I mentioned above.

Prime 95 tests 3 things:
- Memory
- CPU/RAM interface (mobo in all but Athlon64)
- CPU

So, it's most likely that you have some sort of memory issue, with the CPU/Memory interface (mobo) being next most likely, and the CPU being the least likely.

Run the stress tests and let's see what you've got.

FWIW - the distinction between RAM and different types of memory in the system is one that I've made. The documentation that I've read speaks of RAM issues and CPU cache - and doesn't mention the other aspects. BUT, this is just speculation on my part, so we'll have to see how it works for us.

Tried Hot CPU Tester Pro 4.41
The first trial, I had dozens of errors and the program crash after around 5hrs (No Log Saved)
The second trial, a BSOD after around 5hrs (Log & Mini-dumps are attached).

Also tried
Intel Processor Diagnostic Tool(32bit) & It didn't return any errors.

I'll try BurnIn64 (another stress test) & post again.

I'm going to concentrate on testing only the CPU & If it's OK then the problem may be in my RAM (Am I getting it right here??)

Thanks

In another thread today the person had run 17 passes of MemTest without any problems. And they found that the system would have problems with one of the RAM sticks in Prime95 ( http://www.sevenforums.com/crashes-d...ml#post1076674 ). So, I'd suggest the following tests:

Here's a DRAFT Prime95 testing sequence that I'm working on (I've included your links to CPU tests).
Quote:
DRAFT Prime95 testing procedure
This is in case you are getting errors in Prime95 and want to nail down the cause

Run HDD diag and MemTest prior to Prime95

Run Blend test
Run Inplace Large FFT's test
Run Small FFT's test

Run CPU Stress Tests

Swap RAM sticks around per Steps 7 through 10 of this link and run Prime95 (in Blend mode) on each stick/slot: Memory Diagnostics
This is because of issues found in this topic: http://www.sevenforums.com/crashes-d...ml#post1076674

FWIW - I can't make anything of the log file - and the crashes seem to be user level memory dumps of the crash of the system while using Hot CPU Tester (and it's what's cited as the cause of the crash).

Because of the other topic I mentioned, I'd have to wonder if there's an issue with the RAM that MemTest didn't catch. I'd suggest testing the RAM by running Prime 95 (in Blend mode) on each stick individually in each slot.

Hi,

Earlier today I replaced my 2x2GB Chaintech APOGEE RAM,
with 2 x Kingston KVR1333D3N9/2G

I'm running the first Prime95 test (Blend Test) with 15mins duration up till now, I'll post the results at morning.

I hope my problem is now solved.

Prime95 blend test has been running for the past 7Hrs with no errors.

I'll try Hot CPU Tester & post again.

Update to the "DRAFT"(thanks to Reventon), the Intel Core i-series of processors seem to have the memory controller onboard (similar to the Athlon64)
