... The issue is discussed here, Intel's reply is included: Don't know if you read my reply to one of your previous posts Tony, but I've had PAT working on an IC7-G, with four memory sticks, in the past. The board seems to behave in a similar way to the Asus products you mention lsewhere - i.e. you can only run at or near 200MHz memory bus clock to keep performance mode, and memory timing issues also become critical (i.e. if you run two sticks of Brand X, and two sticks of Brand Y RAM, your mileage may vary). Incidentally, as Intel doesn't make boards that can be overclocked, and doesn't officially countenance overclocking, you can hardly expect to get an answer out of them regarding the behaviour of their chipsets when used in these scenarios. -- Richard Hopkins Cardiff, Wales, United Kingdom (replace .nospam with .com in reply address) The UK's leading technology reseller www.dabs.com Get the most out of your digital photos www.dabsxpose.com |

Hi Richard You're correct, I had not yet read the other newsgroup where you said the following: Reading some of your other posts you seem to have got the idea that the IC7 won't run PAT with all four memory sockets populated, period. That isn't accuratet. It will run with PAT enabled on four identical sticks of good quality PC3200 at default (or moderately overclocked) speeds. What you won't be able to do is overclock to the same extent you would with two sticks while keeping PAT and eventually, stability. This, however, is far from a "problem" that is unique to the IC7 series, it's been a factor with virtually every motherboard and memory platform since the PC, and the sport of overclocking, was created. Richard, that is *exactly* the impression I had from reading in the Abit forum: That the IC7 series boards would not enable PAT with all four RAM slots in use, *period*. No one on the Abit board ever mentioned PAT working with all 4 slots in use. There may be a good reason for that: there's a very real chance that they're all overclocking. Since you seem to be having the success and stabilty I'm seeking with an IC7-G, can I ask what brand and configuration of memory you're using? You may want to post on the Abit board, I have a feeling I'm not the only one that thinks there's no way to enable PAT with all 4 slots in use: http://forum.abit-usa.com/showthread...threadid=51428 Thanks for your posts !! |

Richard, that is *exactly* the impression I had from reading in the Abit forum: That the IC7 series boards would not enable PAT with all four RAM slots in use, *period*. That's definitely not a correct summary of the situation. No one on the Abit board ever mentioned PAT working with all 4 slots in use. There may be a good reason for that: there's a very real chance that they're all overclocking. Yep, eminently possible. You've also got the situation where most enthusiasts will go for two sticks because they know this is the best option as far as performance goes. Since you seem to be having the success and stabilty I'm seeking with an IC7-G, can I ask what brand and configuration of memory you're using? The one thing I will say right now is that I'm using two sticks at the moment - two 512MB sticks of Corsair PC4400 to be exact. However, I'm also running my PC at 270MHz FSB with a P4 2.6C and 1:1 CPU:memory bus. The four stick configuration was a stopgap when I got my first IC7-G. The memory would, I'm pretty sure, have been Corsair XMS3200. I found within a very short amount of testing that while performance mode worked fine at or around default memory bus speed, it was very quickly disabled as I raised the FSB. However, with two sticks, as mentioned above, the system maintains full performance when running well in excess of the chipset's design parameters. -- Richard Hopkins Cardiff, Wales, United Kingdom (replace .nospam with .com in reply address) The UK's leading technology reseller www.dabs.com Get the most out of your digital photos www.dabsxpose.com |
