xeguru Posted August 19, 2007 Share Posted August 19, 2007 So here's the question, I ran a QX6700 on a striker extreme which I had set to a 13x multiplier and a fsb of 1100. I orderd in the twinx-8888 ram which I was going to run at 1100 4,4,4,12. I've just changed my processor to the QX6850 which has a FSB of 1333 and I will prob have it over 1400 not sure where the multiplier will end up at. do I still run the ram at 1125 4,4,4,12 or do I go to 5,5,5,12 and increase the speed meaning maybe I should have gone for the 10000 ram instead? HELP:confused: Link to comment Share on other sites More sharing options...
DerekT Posted August 20, 2007 Share Posted August 20, 2007 I think you will find that the timings at 1111 (4-4-4-12) will work fine on this setup. You might also be able to increase the non-linked speed to 1200 and then you would have to raise the timings to reach stability. I do not think that this would be beneficial. Even at 1111, you are in such a rare atmosphere that your system performance on ram read/writes and latencies will be phenomenal. I would try: * AI Tuning: Manual * FSB Memory Clock mode: Linked * FSB Memory Ratio: 5:4 * FSB (QDR) MHz: 1415 * CPU Multiplier: 10 (Edit) * Memory timing: 4-4-4-12-2T * Spread Spectrum: Disabled * LDT Frequency: 4x * Vcore 1.4V * Memory Voltage: 2.4V * HT Voltage: 1.45V * NB Voltage: 1.4V * SB Voltage: 1.6V * CPU VTT Voltage: 1.35V You can then play with the Vcore and other voltages to find stability. You might have to raise your CPU core a bit more. Keep in mind that these voltages are not given in stone. They are an approximation that should allow you to gain boot and begin to tweak/test for stability. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted August 20, 2007 Corsair Employee Share Posted August 20, 2007 XM2S-8888C4 modules are a faster part and will have a wider range of supported settings when over clocking. Hey DereKT How are You? Good to see you posting again. Link to comment Share on other sites More sharing options...
xeguru Posted August 21, 2007 Author Share Posted August 21, 2007 from the setting you suggest I would be running around 2.8 instead of the stock 3? Am I reading that correctly? I was thinking more like 1500 fsb and a multiplier of 10 pulling around 3.75 Link to comment Share on other sites More sharing options...

Good to see you posting again. Hi RamGuy, I'm great, thanks, it's nice to be around the digs again. :biggrin: Link to comment Share on other sites More sharing options...

DerekT Posted August 22, 2007 Share Posted August 22, 2007 You can use Everest Ultimate Engineer Edition to test your bandwidth. I would think that 4-4-4-12 @ 1100 > 5-5-5-12 @ 12xx. Link to comment Share on other sites More sharing options...
