kendogg102 Posted January 19, 2007 Share Posted January 19, 2007 Im starting to OC my new setup and could use some recommended numbers to get the most out of my system. Ive up'd the FSB to 215 so far with no problems in prime95 running two instances. Heres my specs: ASUS A8N32 SLi Deluxe 2 x 1GB Corsair VS400C3 (3-3-3-8) AMD 64 X2 4400+ Toledo Zalman Cu 120mm CPU fan Lian Li V1000 Plus EVGA Geforce 7600 GT Corsair PSU 520W 37 GB Raptor 160 GB Caviar CPU Temp: 32 (idle) MB Temp: 31 (idle) CPU Temp: 45 (full load, 2 instances of prime95) need anything else just let me know!

Test with Memtest and Orthos Prime. If stable then test with an 11 X Processor Frequency Multiplier. I would personally not raise your Vcore past 1.55v. Watch your CPU Core temperature and I would personally keep it no higher than 55C on full Orthos load. You can move it up higher if you find yourself stable here, but keep in mind that this is where you want to test for stability before raising it higher. To raise your CPU speed higher, you would do best to drop the FSB lower and raise your multiplier. In this way you do not lose the kind of DRAM throughput that you would if you raised the FSB since you would very likely have to drop your DRAM to 266Mhz. So after testing for stability and finding your machine stable and not running high thermals, you can lower your FSB to 240MHz and raise your Multiplier to 11X which will give you ~2.64Ghz. Again, test for stability and now if stable, you have some wiggle room from 240 to 250. Raise a few MHz at a time and retest. If you find stability at 250Mhz then you will have 250 X 11 = ~2.75GHz. This will give you an HT bandwidth at 4 X 250 = 1000Mhz, DRAM at 400Mhz and you should be good for the go. Link to comment Share on other sites More sharing options...
kendogg102 Posted January 19, 2007 Author Share Posted January 19, 2007 ok with the settings you recommended heres my temps: CPU- 34 idle / 49-51 full load MB- 32 idle / 36 full load I am running two instances of prime95 and have not yet run memtest on the RAM, but so far it seems very stable.

DerekT Posted January 20, 2007 Share Posted January 20, 2007 Very nice indeed. :) Is that at 250 X 11? Link to comment Share on other sites More sharing options...
kendogg102 Posted January 20, 2007 Author Share Posted January 20, 2007 no that is at your first recommendations of 250 x 10. Im going to start and push it at 11x and 240. Do you think those temps look good for 250 x 10?? Link to comment Share on other sites More sharing options...
DerekT Posted January 20, 2007 Share Posted January 20, 2007 Your temps are most excellent. Link to comment Share on other sites More sharing options...
kendogg102 Posted January 20, 2007 Author Share Posted January 20, 2007 ok with 240 x 11 im at 2.64 core speed Bus Speed: 240 HT Link: 960 Memory Frequency: 188.6 Do these numbers look right??? Shouldnt my HT Link be closer to 1000? and memory freq closer to 200? Link to comment Share on other sites More sharing options...
kendogg102 Posted January 20, 2007 Author Share Posted January 20, 2007 here is a preliminary photo. The CPU is maxing out between 49 and 52 degrees this time. Motherboard is staying the same as before. http://i124.photobucket.com/albums/p16/kendogg102/desktop.jpg Link to comment Share on other sites More sharing options...
kendogg102 Posted January 21, 2007 Author Share Posted January 21, 2007 ok at 250 x 11 = 2.75 GHz heres my numbers: 2 instances of prime95 running. 1 with blend tests and 1 with max power consumption running http://i124.photobucket.com/albums/p16/kendogg102/bench2.jpg im getting the same temps as when i was running 240, 245, and now 250. You would think that i would see a little difference dont you think? Do you see any voltages or anything else that needs tweaked or should i just let it be and be happy with my 2.75 Ghz ?

No, your CPU is running well and you have good cooling. If you are stable at 250 X 11 then hey, don't worry, be happy. That's a fine overclock. That's a good place to be and you are below load temps by a few degrees. That's where I would stay. You could incrementally move your FSB to make 200Mhz on the DRAM. You should have no problem with that. Link to comment Share on other sites More sharing options...
kendogg102 Posted January 21, 2007 Author Share Posted January 21, 2007 i have noticed one thing since overclocking. Everything is stable but if i choose "restart" from windows the machine shuts down and then POST's. Right after POST it goes to a black screen with a blinking cursor. Cant do anything from this screen so i power down and then power up. It then starts up and boots windows fine. This only happens when I restart from windows.

DerekT Posted January 21, 2007 Share Posted January 21, 2007 Yes, I had this issue as well when I had the A8N32-Sli. It very likely has to do with the high overclock. My "fix" (such as it were) was to choose "Shut Down" and then press the on/off button to restart. I certainly wasn't going to drop the overclock :p: Link to comment Share on other sites More sharing options...
kendogg102 Posted January 22, 2007 Author Share Posted January 22, 2007 one last thing, do you think that i could try to get a command rate of 1T out of my memory? If so do I need to relax the timmings? Recommendations? Oh and when you had your A8n32-sli, what were your best OC'd numbers? Just curious :) Link to comment Share on other sites More sharing options...
DerekT Posted January 22, 2007 Share Posted January 22, 2007 one last thing, do you think that i could try to get a command rate of 1T out of my memory? If so do I need to relax the timmings? Recommendations? It's a dice throw. If I were you, I would set to 1T and Memtest. If it fails, then you are pretty much out of luck but you can try raising the Bank Cycle Time (Tras) to 12 and then 15. This can often smooth out the strobe cycle and allow the 1T Command Rate stably. Oh and when you had your A8n32-sli, what were your best OC'd numbers? Just curious :) I had so many processors to test on that board. Let's see: A64 3000+ Venice at 2.65GhzA64 3700+ San Diego at 2.9GhzOpteron 144 at 2.8GhzOpteron 148 at 2.9GhzA64 X2 3800+ Manchester at 2.6GhzOpteron 165 at 2.75GhzOpteron 170 at 2.8Ghz That's about it.

kendogg102 Posted January 23, 2007 Author Share Posted January 23, 2007 Ok this is where im gonna call the OC'ing quits. Quite respectable i think. Maybe ill give the memory a go on 1T for the command rate later. Heres my final numbers, and my CPU temps were between 51 and 53 full load 2 instances of prime95 running large FFT's http://i124.photobucket.com/albums/p16/kendogg102/bench3.jpg Thanx for you help derek!

DerekT Posted January 23, 2007 Share Posted January 23, 2007 You're very welcome. Great voltages, good load temps and 2.8Ghz on a dual core AMD is more than respectable. Well done. :D: Link to comment Share on other sites More sharing options...
