sack_patrol Posted October 1, 2010 Posted October 1, 2010 2600 should be as high as you'd need to go. If it doesn't work with that, it probably won't work with 2800 or 3000 or whatever. Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted October 1, 2010 Posted October 1, 2010 Little bit of an update still running it at 3.8 x19 CPU Multiplier 1.4000 , but i now havee my NB at x13 (2600) running at 1.2500 from x12 (2400) at 1.1000 Seems to be holding steady, kinda scared to go higher wait I'm confused so the NB is at 2400 or 2600 now?

sack_patrol Posted October 1, 2010 Posted October 1, 2010 wait I'm confused so the NB is at 2400 or 2600 now? 2600, he said that he changed from 2400, to 2600 basically. Share this post Link to post Share on other sites More sharing options...
IVIYTH0S Posted October 1, 2010 Posted October 1, 2010 2600, he said that he changed from 2400, to 2600 basically. why would he raise the NB just because anyway, I just realized that you said coolermaster V8 which isn't that great of a cooler. You may be limited by temps Share this post Link to post Share on other sites More sharing options...
Meteora Posted October 1, 2010 Posted October 1, 2010 LIke i said was going with a coolermaster theme or i would have chose differently, but yeah v8 isn't the greatest.. I have it running at - CPU Multiplier - X19.5 CPU VID - 1.4125 NB Multiplier - x13 NB VID - 1.2500 Memory VDDQ - 1.500 CPU VDDQ - 1.432 NB Core Voltage - 1.100 CPU HT Voltage 1.200 HT Speed - 2000 NB Speed - 2600 Core Speed - 3900 Its holding at 53, and been running Prime95 for about 10 minutes now, gonna let it keep running while i am at work and that should be about 8hrs, wish me luck!

Drdeath Posted October 2, 2010 Posted October 2, 2010 You can easily hit 2600-2800MHz on NB fequencies, however get your overclock good at 2400-2600MHz and keep everything stable and then toy with the NB. Share this post Link to post Share on other sites More sharing options...
joel.monteiro Posted October 2, 2010 Posted October 2, 2010 (edited) Increase ur voltage,if temp are below thermal limit. Edit-Run Occt its a bit more powerful than prime,therefore u will most likely get errors on Occt .

Drdeath Posted October 2, 2010 Posted October 2, 2010 Depending on the multi, the NB should be between 2400-2600 until you find a decent OC. Play around with multi's sometimes there is a magic FSB(HTT). When you change the multi, the HTT and NB changes so you need to adjust both along with Hypertransport and memory dividers.

Skoree Posted October 2, 2010 Posted October 2, 2010 You should seriously look into getting a new Mobo. Right now you're only getting two X8 lanes for your 5870's. The 790GX chipset doesn't do full dual X16 lanes. Either the 790FX or 890FX is what you should be using, otherwise you're severely limiting your GPUs' performance. I just upgraded my rig to the 890FX. It does dual X16, plus an X8, and an X1 lane. I only use 2 5850s so its more than adequate. I also have 955be and haven't seen any noticeable difference in performance once I got over the 3.55-3.6GHz range. I'd say stay around 3.6 and start working on maxing your memory freq and timings. I'll be you'll see better performance and better temps. Food for thought! Share this post Link to post Share on other sites More sharing options...
Drdeath Posted October 2, 2010 Posted October 2, 2010 2 x 16X does not yeild any more performance than running in 8X. The bandwith is never fully used. Share this post Link to post Share on other sites More sharing options...
paulktreg Posted October 2, 2010 Posted October 2, 2010 2 x 16X does not yeild any more performance than running in 8X. The bandwith is never fully used. There's a very small performance loss of 2% when running 2 x 8X over 2 x 16X which is nothing in the real world is it? There's an interesting article here for anyone that's interested, the performance when running two 5870 at X4 or even X1 are really unexpected?
