rounding error prime95 blend North Kingstown, Rhode Island

I wasted weeks of my life trying to make my stupid computer 'prime' stable, and for what? When some power supplies are pushed too hard, their voltages droop.

Searching the web, it seems that this is a memory issue and that it can be caused by a a faulty unit, wrong voltages and/or timings amongst other things. I've seen drops of 5 degrees centigrate in Prime95 just by cleaning the dust out of a CPU heatsink. Edit: To clarify, I don't mean either of those as long term solutions, but just as a way to get a better idea of what the problem is. Livingroom rig Now I have a good feeling that setting it manually may solve my problems, because things were pointing this direction and then I find it was indeed incorrect.

Blend really is the ram and cpu together, but you said you passed memtest AND you passed small ftt's... solved My laptop give me an error saying I'm low on memory but its at 50% or lower More resources Tom's Hardware Around the World Tom's Hardware Around the World Russia I'm no expert, so let me know if I'm talking crap. If you want to be thorough in testing the CPU, the RAM, and the CPU/RAM interface then you should really run both Prime95 and MemTest86.

Sign in here. Prime95 is not actually capable of doing FFTs of any arbitrary size. You will need to do some work here to be confident when doing it. Don't leave it on auto. I went and put the bios back to where it was before I started getting these issues, going to see if it stops the errors, did you

You can assign that instance of Prime95 to a particular CPU by unchecking the "Let program run on any CPU" box.

This one is onto the 4th test and still no fails, though I anticipate working it for another while. If you're running a CPU like the Athlon 64 which has its CPU/RAM interface integrated into the CPU, then if your RAM has passed tests you can pretty much blame your

Performance & Maintenance Prime95 Instant BSODHello. Another possibility for me is that the stock cooler, being a bad cooler, forces the CPU to throttle and keeps the speed lower. I.4 OS Windows 7 Ult. CPU overheating is a common cause of Prime95 failures.

Did you put the paste (or thermal pads)? Try 14.7.

When I install the Hyper 212 EVO cooler on my CPU and run Prime95 Blend test, then the program immediately shows a fatal error "rounding was 0.5 expected less than 0.4..." It runs hotter than the small FFTs test because that test isn't accessing RAM very much so it's not heating up the CPU/RAM interface and that part of the CPU consumes Although it is not a MUST, it is at least a SHOULD, specially in cases where the CPU/mobo/memory subsystem is put to stress regularly. You can see my CPU is getting about 1.2 volts, and is in the upper 60's right now.

If you're running Windows 2000 or Windows XP then you can also check whether the CPU is fully utilized in the task manager. According to specifications, the 12 volt rail should always be 12 volts plus or minus five percent which means from 11.4 to 12.6 volts. It's just a possibility and there's no easy way to be sure without replacing it.

It's not a thorough RAM test but then neither is the blend test and blend doesn't stress the CPU as much as in-place large FFT. Then alternatively a blend test will do both CPU and Ram.Personally I use memtest (dos based program) to test my mem, and Prime for CPU stability. You shouldn't have to do that unless you have four RAM sticks.Do this first: Check your VTT/VCCIO voltage -- if it's not 1.15v, increase it to that.If it still gives errors, You shouldn't use Prime95 as a RAM test.

The "Min FFT size (in K)" and "Max FFT size (in K)" allow you to pick the minimum and maximum size of the FFTs done in the test. Prime95 Rounding error. Sorry for not linking the ram though G.SKILL Ares Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 It's been going for a little over an hour now with no That usually causes the computer to crash or hang although occasionally it can just cause errors.

In that case, you can probably check the 12 volt rail of your power supply with a motherboard monitoring program. The CPU is normally running at 3.4 GHz but is overclocked to 4.5 GHz. The program is free and you can download it from here.

Running any other programs at the same time will reduce your processor load. Rounding. So on those CPUs, the CPU/RAM interface is the front side bus. The time now is 09:03 PM.

The blend test tends to run a bit cooler than the in-place large FFTs test probably because the blend test is sitting and waiting for the memory accesses longer than the My System Specs OS Windows 7 64 Ultimate meuqsaco View Public Profile Find More Posts by meuqsaco 13 Jan 2012 #7 meuqsaco Windows 7 64 Ultimate 27 posts The "Small FFTs" test uses relatively small FFTs which can fit into the CPU cache.

In case you're interested, "FFT" stands for fast fourier transform.
