Arrow More stressful than Prime95

You might want to run the latest IntelBurn test. It's even tougher on the processor than Prime95, and identifies calculation errors in an hour or so. Crank the memory setting up close to maximum,...

Minor bugs when using #workers < #cores

I ran into a couple of less than optimum issues when running 2 workers on my 4 core i7 920 processor. (My electric bill has sent me on a frugality hunt)

Thumbs up Thanks for the quick fix

When checking my latest benchmark, I noticed that both the Prime95 version and my clock speed are now being reported correctly. Thanks for the quick work.

System RAM won't have much of an effect

The thrashing George is talking about will only affect programs that are highly cpu limited and are processing huge amounts of data e.g. Prime95.

If you're running a browser or other light cpu...

Definitely looks like a hardware issue

How good is your 850W power supply? Some of the generic versions have some stability and noise issues with their 12V buses that can trigger memory errors.

Can you check your Northbridge...

Closer here

Under 26.3b3 (64-bit) the estimates for ECM work in the 5.4M range are about 3:05 apart in my assignments. Actual time is ~ 4:00. That's closer than I used to see at least.

Same speed, same performance

At the same speed, the i5 and i7 deliver pretty much the same throughput on Prime95. The i7 has a small edge because it usually comes with triple channel memory compared to the i5's dual channel.

Red face 32 bit allows me to shoot myself in the foot

On the 32-bit version 26.3b4 (and previous builds), setting the memory maximum too high can kill a worker. I set my max mem to 2000 MB. Near as I can tell, when Prime 95 (x86) got up to allocating...

Stage 2 is 60% of Stage 1

This is on ECMs in the 5M range.

Thumbs up 26.2 finds ECM factor
