OC Challenge Hello, been trying to OC this set up... to no success. :doh: Have posted to other boards but don't seem to get any direction. So here is what I got *** Manufacturer ASRock Model 890FX Deluxe3 Version Windows 7 PRO Chipset Vendor AMD Chipset Model 890FX Chipset Revision 02 Southbridge Vendor AMD Southbridge Model SB850 Southbridge Revision 40 AMD Phenom II X4 965 Stepping 3 Revision RB-C3 Type DDR3 Size 2048 MBytes X2 Manufacturer Mushkin Max Bandwidth PC3-10700H (667 MHz) Part Number 991782 (996782) SPD Ext. EPP ### Type DDR3 Size 4096 MBytes Channels # Dual DRAM Frequency 668.0 MHz CAS# Latency (CL) 9 clocks RAS# to CAS# Delay (tRCD) 9 clocks RAS# Precharge (tRP) 9 clocks Cycle Time (tRAS) 24 clocks Bank Cycle Time (tRС) 33 clocks Command Rate (CR) 2T ATI Radeon HD 5850 Series Memory 1024 MB Memory type 2 Driver version 8.861.0.0 *** If need more info holler *** So I know the CPU will over clocked cause it came from another build, but could get the mobo in time. Would be happy running 3.6 ~~~~~ 3.8 would be awesome I am believe its a memory timing issue, but having a heard time understanding timings. Also this mobo can adjust everything!!! So the amount of adjustments loose me also... I have had this run prime 65 @ 3.6 for 1/2 hour only tol crash 4hrs later. Any configuration changes and will let you guys/ girls know the result !!! :thumb: Thanks |
Official Phenom and AM2/AM2+ Overclocking Guide Okay that is a must read if you have not OCed AMD before. What combos are you using for the overclock? FSB / Multi / Divider and voltages? Once I have more info I can help more. |
Well I had done a simple multiplier OC on the PC that CPU came from, same with my old. Barton & clawhammers.... So I guess not concerned on how I achieve 3.6 just so it is stable. May seem odd but I never had a mobo that would go into the detail of adjustment. So if you are thinking I haven't done my home work, I can post the many links. Cause everything I have read ... posted or otherwise doesn't seem to work. Reason I lean to memory is the fact that I started this build with a x3. What the timings call for on site wont let the computer boot. So currently running defualt. Any simple of tool whether in Bios or AMD will crash within 5 minutes. thanks |
What's your vcore at? I can push my phenom II 940 to 3.7 but thats the wall for it, you shouldn't have any issues at all to get to 3.8, or even 4. |
Check your voltages all around and make sure you have them locked down and not on auto. Same thing with memory. I have my 965 @ 4.3ghz right now but I just went with a multiplier OC. Haven't taken the time to really OC. |
ok I can do that.... I digging out my old notes and noticed this... ASrock has a bios utility that is either 5 or 10 % what it changes is HT from 200 (auto) 210 (5%) 220 (10% this is a no windows starting BSO instant) Muskin Memory is 1600 but at defualt is 9-9-9-9 24 at 668 (1300???) So I did lock memory at 7-9-7- 24 at 800 (1600) which is on the package... I can see the advantage of a slight bump as am retesting with 3Dmark eleven at stock speeds scored 3856 up to 3.6 (currently doing this by hand X18 and HT of 200 ) 3867... I am also wondering if this bench marking is not prime 95 " :angry2:happy" cause it will crash within 2 minutes but in Overdrive or 3d mark will run complete 15 minutes or so??? Hope that is all making sense??? |
Have you tried bumping up the voltage? that's crucial to keeping a stable overclock. |
Update... Although still nervous to run prime95 I got 3.6 @ 4.125 v and was able to use amd overdrive to test... so far so good??? Now part two... I attempted 3.8 with the HT at 200 using the multiplier and voltage. keeping to 7-9-7-24 1600 memory timings. I read never go over 1.5 !!! 3.8 started to stabilize at 1.4375 without an BSO but stopped a 1.475, it just would not run the overdrive tests for more then 3 minutes... :angry2: So it seems I made a small step forward :biggrin: Any thoughts on the next???? |
Are you monitoring your CPU VID? Most AMD chips should stabilize at 4ghz around that voltage, you should be stable considering your board appears to have fairly robust power delivery. Open up CPUZ then fire up prime95/LinX and look at your VID. If it drops, take note of how much and compensate for that in your BIOS settings. If it's too big of a drop, (requires more than 1.5v set in BIOS) enable LLC. (load line calibration) Keep in mind that LLC will enable higher current and sometimes buffer your CPU with a higher voltage than what you set. |
ilya... I see that the Core Voltage is at 1.392, and drops 1.384 when running prime95, before BSO I don't see any thing in the Bios that gives me that adjustment or LLC? The computer was doing good last night but now cannot keep it running :sad: So I back to the thought its a memory issue??? Adjusted to 668mhz (1300) auto (9-9-9-24) Guess we shall see.... Thanks everyone so far |
