Russ_64 Posted March 9, 2005 Share Posted March 9, 2005 My rig as listed below is running stable at 216 and at 1:1 (DDR 432) but as soon as I go higher I get XP BSOD's after a few minutes. Tried 218 and 220. Someone on the MSI forum suggested that 222 maybe a sweet spot (?). Also have seen on this board that this memory is capable of DDR500. My MB auto detects this RAM as 200-3-3-8-1T, I tried the stated timings of 3-4-4-8 but XP blue screens during startup ?? Any ideas what I should try next ? :confused: Thanks.

Yellowbeard Posted March 14, 2005 Share Posted March 14, 2005 When you are OCing, have you lowered the HTT speed? Not sure what MSI calls it but it is the Hyper Transport setting. On an ASUS rig it is given in increments of 200, ie: 200, 400, 600, 800, and 1000. It is set at 1000 for stock. So, try your comparative setting and try something lower than stock. Mike.

bestmancajun Posted March 19, 2005 Share Posted March 19, 2005 Is your pci locked down? If your pci is higher then 34 those drives will fail. Blue screen of death... Link to comment Share on other sites More sharing options...
Yellowbeard Posted March 19, 2005 Share Posted March 19, 2005 Is your pci locked down? If your pci is higher then 34 those drives will fail. Blue screen of death... AH!...Good point also. That's right about where a problem occurs (215-220mhz) if the PCI lock is not working. Could be either, PCI lock or HTT. Mike. Link to comment Share on other sites More sharing options...
jsteel44 Posted April 1, 2005 Share Posted April 1, 2005 Is your pci locked down? If your pci is higher then 34 those drives will fail. Blue screen of death... you kidding? most pci devices can usually sustain a 38-40MHz bus, 34 is minor, granted some really cheaply made or crappy hardware can fail that early at 34-35. PCI lock should be on, methinks its the HTT multiplier too high. Link to comment Share on other sites More sharing options...
Jackolantern Posted April 3, 2005 Share Posted April 3, 2005 The Neo has a working Lock. You need to lower the HTT from x5 to x4, but not untill you get to around 10% overclock they can handle that. Use the plus and minus on the keyboard to change the HTT on there. It will sometimes lock up if you hit enter. Open the bios, Highlight Cell Menu, then hold shift, hit F2, THen hold alt hit F3. If it worked you will be highlighting the first item in the menu instead of Cell Menu This opens the easter egg in the cell menu. It will allow you to lock/unlock the AGP/PCI locks. Change the AGP one from auto to disabled. The PCI one should stay on auto, also find the AGP side band addressing thingy and turn it off too, I dunno why that last thing, but it seems to have halped here. Good luck Jack Link to comment Share on other sites More sharing options...
G-MAN Posted April 4, 2005 Share Posted April 4, 2005 HTT is the buss speed or FSB 222,HT is the HTT multiplier, 1X,2X,3X,4X,5X. If it is still at 5X you need to lower it,5X 222 HTT is 1110 which is to high. Link to comment Share on other sites More sharing options...
Russ_64 Posted April 5, 2005 Author Share Posted April 5, 2005 Thanks - glad to hear that I should be able to go higher. I will try to lower the HT to x4. Am back at 212 now as Win XP 64 bit did not like 216 ! By the way my AGP is set to 67 / 68 so PCI lock should be on. Will be installing a water cooling rig in the next few weeks. So will play with it more after that. Link to comment Share on other sites More sharing options...
