chennhui Posted April 14, 2005 Posted April 14, 2005 RiZZo, I do not know whether your PDP like 2.9v. Because my RAM only stable at 2.9v. Share this post Link to post Share on other sites More sharing options...
chennhui Posted April 15, 2005 Posted April 15, 2005 Running 180 memory_divider @252Mhz 2.5-3-3 or 150 memory_divider @210MHz 2-2-2 yielded better performance than @280Mhz 2.5-4-4 1:1. Share this post Link to post Share on other sites More sharing options...
lmmaudio Posted April 16, 2005 Posted April 16, 2005 These are my notes. As for BIOS version I started this thread which could also help somehow... FSB Bus - 259 LDT/FSB - 3 LDT Bus - 16/16 CPU/FSB - 10 PCI-E - 101 CPU VID StartUp - 1.425 CPU VID Control - 1.475 CPU VID Special Control - 110% LDT voltage control - 1.4 Chip Set Voltage Control - 1.8 DRAM Voltage Control - 2.9 DRAM Freq - 200 CPC - Enable Tcl - 2.5 Trcd - 4 (no way 3 above 250) Tras - 6 Trp - 3 Trc - 8 Trfc - 11 Trrd - 2 twr - 3 Twtr - 2 Trwt - 4 Tref - 4708 (crazy timing here. I can do any setting with Interleave disabled, other wise very picky... 16, 32, 64, 128, 780 only) Twcl - 1 Bank Interleave - Disable (loss of bandwith here, but Enabled can't seem to work memtest above 253) Skew Control - Decrease (have no idea what this setting is about... eihter way seems to make no difference at all) Skew Value - 96 (or this one) Drive Strenght - 7 (can do 8 also...) Data Drive Strength - 4 Max Async - 7 Read Preambule - 5 IdleCycle Limit - 256 Dynamic Counter - Disable R/W Queue Bypass - 16 Bypass Max - 7 32 Byte Granularity - Disable I can memtest these settings up until at least 270 for 12 hours. Being OCCT and memtest stable I still can find no way to get it at 260x10 :mad: Share this post Link to post Share on other sites More sharing options...

robowang Posted April 16, 2005 Posted April 16, 2005 Using bios 414-3 and 2x512 Patriot 3200XBL Just got them four days ago. Almost immediately, they were running 5 pass Memtest stable at 2.5-3-3-6, HTT 285. With 8-10 hours of tweaking after that, still can't get them stable at hTT 290. Still have a few settings left to try. HTT 285 at these settings aren't bad, tho. So, spent this afternoon getting them to run HTT 300 at 2.5-4-3-8. Settings are: HTT 300 LDT X3 Cpu Multi X7 PCE-I 100 Vcore Startup 1.475 Vcore 1.374 Vcore Special 110% LDT V 1.3 Chipset V 1.7 Vdimm 2.9 Ram Multi 200 1:1 CPC EN Tcl 2.5 Trcd 04 Tras 08 Trp 03 Trc 11 Trfc 22 Trrd 02 Twr 02 Twtr 01 Trwt 03 Tref 4708 Twcl 01 Bank Inter EN Skew Control Auto (Off) Drive Strength 07 Max Async Auto (8ns) Read Preamble 05 Idle Cycle 256 Dyn Counter DIS R/W Que Bypass 16X Bypass MAx 7X 32 Bit Gran DIS In Memtest HTT 300 was stable except for test eight getting 10-60 errors. After changing setings for a while with no luck, swapped memory in the slots (still 2 orange, just changed sticks around) and stable at HTT 300. Had Dram Strength at 5. Changed it to 7 and now stable to HTT 310, but not HTT 315. Still have a lot of settings to tweak. I think 315-320 will work. 3 1/2 hours of Memtest passed. In Windows at 300 X 8 = 2400MHz 1.275 + 123%, 3DMark 05 passed 6 loops, Prime Stable on blend for 2 hours. Everest memory tests are Read - 7378, Write - 3214, and Latency - 39.2. Sandra Mem Bandwidth 7213, CPU Arith - 10560 (cpu at 2400MHZ). My 3200+ Winchester has a terrible mem controller and will only run 2520 stable at 1.54 vcore. Waiting for my 3700+ San Diego preorder. 11X multi. Share this post Link to post Share on other sites More sharing options...
wa-da-ya-no Posted April 16, 2005 Posted April 16, 2005 Have mine at 300mhz 2.5-3-3-7 @ 2.7v Share this post Link to post Share on other sites More sharing options...
robowang Posted April 17, 2005 Posted April 17, 2005 I worked on tweaking for 2.5-3-3-8 to get a good HTT 300. I think it may have come around. It is doing the Memtest now and it's on the 3rd full pass. I upped the Tras from 6 to 8 and this morning I swapped slots on the memory as in my earlier post. I am amazed at this ram. I was going to buy Gskill LE but it was out of stock. This was 60.00 cheaper and from what I am reading, on the average is as high of performance. Of course this is on my system now. I will probably have to start all over when I get the San Diego core, IF it ever gets available Share this post Link to post Share on other sites More sharing options...
chennhui Posted April 17, 2005 Posted April 17, 2005 Nice work robowang, 2.5-3-3 at 300. Have you passed Prime iterations with 4096 FFT length (~10 hours prime)? If you did, then I think you memory latency will be very low (<37ns) at such aggresive timings. Do let me know. I just tried lmmaudio's suggestion on Tref of 4708. It really help scaling memory speed up. Share this post Link to post Share on other sites More sharing options...
robowang Posted April 17, 2005 Posted April 17, 2005 I haven't started OS stressing yet. Went over 4 hours Memtest full, but that doesn't mean it'll 3D and prime. Tomorrow i'll see if it's stable to my satisfaction. Gut feeling is it will be, as I am only at 2400MHz due to poor Winchester.

robowang Posted April 17, 2005 Posted April 17, 2005 Finished an overnight DVD re-encode (8 1/2 hours 100% cpu load)OK. Haven't run Prime any more than stated above. I am seeing if the system will be stable at my normal work habits. Has been running some type application for over 16 hours right now, no BSOD or errors. The thing is, it doesn't feel "fragile". Do you know what I mean? It's like when it's not completely stable, there's a feeling that even opening a browser will crash it and you flinch a little when clicking a button. Am I the only one who has these "moments"? I guess 8-10 hours a day on a PC effects a man. :drool: Share this post Link to post Share on other sites More sharing options...
komodo Posted April 17, 2005 Posted April 17, 2005 Hi, these are some settings for all you PDP XBLK owners to try: XBLK super pi XBLK A64 Tweaker settings My stuff likes 3.0v but give them less if yours don't respond. Make sure bank interleave is enabled. Drop your CPU multi to 8 X 300HTT if you're not stable@9 X 300HTT. Hope this helps Share this post Link to post Share on other sites More sharing options...
magg Posted April 18, 2005 Posted April 18, 2005 Hey komodo...could you post those A64Tweaker settings on the newest version? [0.60 beta]. That's the one I have, and there's different options that aren't shown on 0.50XT and vice versa. If not, it's all gravy. Share this post Link to post Share on other sites More sharing options...
