P95 blend can be a lot harder to stabilize than IBT,OCCT or AIDA64 without knowing your other setiings like ram speed,timing or NB I would say you probably need to be in the 1.52- 1.54v rnge to get P95 stable at 5.0 and that's assuming you have a decent 8350

It's funny you say that cause I have though the opposite before, I almost always run the HT a lot faster than my NB. I know it's almost backwards to the deneb nd thuban but that's just me.

lowered stress on multiple circuits

you are essentially cutting down the bandwidth available to the PCIe bus and so a small part the memory bus.

if you don't need the bandwidth and don't use it, it will likely feel like a performance boost as it will allow the cores to clock slightly higher. (those 8ghz+ clocks are on lower then 2000 ht and super low speed ram to take the stress off those parts of the circuit.)

Those temps are forced throttling. When the chip forces throttle due to other issues.

Hello all, just finished a nice new team red build - I've been on intel/nvidia side for a while and really wanted to give AMD a try since the last time I had it was back in the Athlon XP days and before that duron (l2 bridge pencil overclocking ftw!) biggrin.gif

Anyways, I enjoyed the cheap microcenter prices for my 8320 @ $99 - I went with the Gigabyte 990FX-UD3 motherboard as it had a lot of good reviews and complimented the rest of my build with the dark tons - truly an awesome looking board.

http://valid.canardpc.com/v0hyfu

So far I had an issue at stock clocks and configuration where about half of the cores would downclock themselves to ~1.2GHz while running prime95 max heat mode which I think was the reason for BF4 only pulling 30% on my dual XFX R9 270Xs in Crossfire mode.

I OC'd to 4.5GHz using some guides I found on here and it feels like I got a real good chip as I got 4.5GHz @ ~1.35V, don't know if this is good or not. I didn't touch HT Link speed or BCLK, just ratio and disable turbo boost and set my cpu clock to +0.025 with a Medium on LLC.

I've got the chip under a Cooler Master Seidon 240M inside of a Corsair Carbide 540 Air that keeps it under 50C even under full load.

If I need to post more information I can in order to be an official member biggrin.gif

Guys I may need some help here. I was running my 7950 mining (undervolted to 1.150 from 1.188) with my 6850 playing BF4 (undervolted to 1.140 from 1.150) and was also recording. Basically I was pushing every part of my rig to maximum usage and 10 minutes later, my computer shut off. I worried it may be by PSU dying but how can i trouble shoot this? Could it have been my PSU hitting its thermal limit and shutting off? How can i know?

the throttling is probably the bios which does that so your board does not blow !

I had a similar problem with my rig when trying to run IBT AVX at 5ghz with very high voltage. PC would just shut off after a few minutes.

It turns out my OCZ ModXStream Pro 600W was overloading on one of the dual 12V rails and triggering overvoltage protection, shutting the unit off. The only way I found this out for sure was to replace the power supply with a (much better) Cooler Master V1000, a Seasonic unit. Now under the same circumstances, my machine doesn't shut off anymore.

Really, the only way to know for sure is probably to try with a different power supply (Preferably one with very high wattage on a single 12V rail).

You can always pm Shilka and ask him about it too.

EDIT: Overclocked 83xx can draw up to 300W, hell mine draws 210W at idle at 4.7ghz. 7950 mining is probably 300W, and a 6850 running BF4 is another 200W or so, all on a 750W power supply. That's probably your problem. Get a bigger power supply.

The only way I found this out for sure was to replace the power supply with a (much better) Cooler Master V1000, a Seasonic unit. Now under the same circumstances, my machine doesn't shut off anymore.

Really, the only way to know for sure is probably to try with a different power supply (Preferably one with very high wattage on a single 12V rail).

You can always pm Shilka and ask him about it too.

EDIT: Overclocked 83xx can draw up to 300W, hell mine draws 210W at idle at 4.7ghz. 7950 mining is probably 300W, and a 6850 running BF4 is another 200W or so, all on a 750W power supply. That's probably your problem. Get a bigger power supply.

Hmm I may just buy a bigger case that i can run dual PSU's in. I have my old cx600 Ican run the 7950 off that i suppose.
