Hi everyone,
If possible i want to know if i enabele the optinon in my bios "one core per compute unit" or disable.
i have fx-6100 buldozer and a ga-990xa-ud3.
thank you

1. Well not necessarily on yours. I think its a general rule of thumb. The right way to do is look up your RAM's IC's and find max voltages from the makers of the chips. It seems that 1.7v is safe for 24/7 use based on others opinions I linked earlier.
2. No VRM cooling. No heatsink no fans. You're gonna wanna change that, dunno if xd_1771 will weigh in but look here for information regarding vrms.
3. Large PSU doesn't mean great. However I don't think it would be a problem despite its review here. Expensive large wattage doesn't mean it delivers voltage within spec/ripple/wattage. However I don't think it's really a problem...
Update on the MemTest with the voltage boost?
Overclocking... Iono how far you can go with gigabyte d3 without mosfet/vrm cooling. Again, read the link.
1. OK I will take it easy when I do the memtest. I'll try up to 1.6V unless I hear different from someone.
2. Yeah, that's what I heard about this mobo after the fact. Now, I'm just trying to get this thing stable on STOCK settings, shouldn't it handle bulldozer? Maybe the FX 8150 is just too power hungry even on stock settings for this poor $90 mobo? Also, has anyone had any bios settings end up kind of screwy with everything on auto?
3. Understoood. It seemed sufficient though, and this system should be running WELL under the rated load. It's also a certified unit. Maybe that doesn't mean much.
I can't run the memtests until I get home tonight. I'll run them overnight and report back. For anyone coming in late, my original post was #883.

Alright I ran memtest last night at 1.6V on the DIMMs. Still got plenty of errors. frown.gif They are always the same error though- Block Move, err bits 0x04000000. Does that have any significance? So basically at this point my RAM fails regardless of slot, and regardless of single/both DIMMs.

Anyone have any more thoughts on this? FlashFir thinks it's either RAM, mobo, or PSU. My theory is that the mobo just can't handle an FX 8150's power draw or something. Thanks for the help guys smile.gif

I put ram voltage up to 1.65v and all memtest errors have gone stable now i think AMD boards need more dram voltage than intel .

That's obviously not true for all AMD boards... It's probably faulty RAM or motherboard. They should run @ stock speeds & voltages. If they don't, it's messed up.

Whether it's worth 1 week >= of RMA waiting time? That's a decision that we gotta make tongue.gif

Yes true but my ram 16 GB of corsair xms 3 can run from 1.5v to 1.65v and corsair recommend 1.65v for AMD boards. I did not know this so left voltage at 1.5v and got memtest errors but now it’s at 1.65v its stable.

This is from corsair technical support worked for me I have 16gb of CMX8GX3M2A1333C9 RAM @1.65v 24hour pass on memtest.

The CMX8GX3M2A1333C9 RAM is rated to run at voltages between 1.5-1.65 V. the default DDR3 RAM voltage is 1.5 V. Some mobos require higher RAM voltage to run at higher than the CPU OE rated RAM frequency. The CMX8GX3M2A1333C9 RAM should run @ 9-9-9-24, 2T, 1333 MHz. @ 1.5 V.

If you plan to use this with your AMD 965 BE CPU you can use any voltage between 1.5-1.65 V that allows your PC to run stable. If you plan to run this on an Intel mobo it may desire the RAM to run at 1.5 V.
1.5 V.

1.5 V.

You know the many of the XMS3 series are required to run @ 1.65v... And no other brand or line requires 1.65 on AMD & 1.5v on Intel.
I think it is more accurate to say it has to do with the binning of the XMS3 chips & how how they interact with AMD vs. Intel boards.

Yes just bulit a new system with fx-8120 and GA-990XA and thought there was something not right but now i have the memory voltage at the correct setting it is a very fast setup love it.

Can someone who owns the GA-990XA answer this for me please? How many fan headers are there on the board? I looked at the picture and watched a video and only saw the CPU fan+2 more, but maybe I'm just blind because the Gigabyte website says it has

1 x CPU fan header
2 x system fan headers
1 x power fan header
