Prime 95 Fatal Error Help

post #1 of 12

Fatal error rounding 0.5 expected less than 0.4
Ran prime on blend settings and it gave me this error and i know how Blend uses a lot of RAM testing.
Does this mean that I can RMA the RAM and expect these errors to stop?

Not so fast there, you need to throw some more information onto the table first. I mean, what CPU are you using here? What motherboard and RAM? Any overclocking? And finally, are you seeing other issues besides just a rounding error in prime?

Amd 8350 Vishera No O/C.
Using a Gigabyte 990FXa UD3 mobo
Ram is 1866 mhz Gskillz Ares 2x4gb
I am getting Whea-Logger id 19 errors in Event Viewer and I saw on some forums that the most potential problem is the RAM
Already made a clean install of Win7 64 bit.

Also sometimes saw the Fatal error resulting sum.

Drop your ram speed to 1600 in the BIOS and retest, see if you get these same errors. If you still get errors, go to Control Panel/Administrative Tools/Windows Memory Diagnostic and run a full, deep scan (you'll have the option to choose how thorough it is once you reboot and get to the actual test). If that comes up with errors, you've got a bad stick. Take one of them out, and redo the test. If you STILL get errors, swap the sticks. Still errors even then? Swap the memory slot the stick resides in. If you still have errors after that, then post about it. It would indicate something more sinister than just faulty memory.

The Whea Logger errors give more detail about the event. For example, if it says anything about "cache hierarchy", the CPU needs more volts. Most probably it's either the RAM, or the CPU needs more juice.

Yah it is a cache heirarchy. I have my cpu at auto voltage in bios and right now my ram is set to 1600mhz because i have auto timings and voltage.

Yea what settings your motherboard is setting your RAM at is crucial. Run memtest overnight with you setting it directly at the RAM's rated specs.

Most probably the "auto" setting on your CPU isn't enough. You need to see LLC setting and see how much voltage effectively the CPU is receiving. Cache hierarchy is common error when undervolting too much.

Another possibility is there is a glitch with Cool N Quiet and related features (C1E state etc). You must try different combinations in BIOS for that.

I checked and its running at 1.5V which is the recommended voltage for it.
