leftorium Posted November 22, 2005 Share Posted November 22, 2005 hi - first foray into manually clocking memory so pls bear with me the above is ddr400 which i took to mean 400 MHz - when i install 2 sets in dual channel mode in my asus k8n sli - bios 1013 it auto detects a speed of 333MHz - when I read the forum it suggests manually setting at 200MHz I assume in line with my processor - when i try to set at 400MHz the machine won't boot and needs a BIOS reset. when i set at 200MHz everest home edition reports the RAM as PC1600 - should i worry? - shoudl I be trying to push to 333 or 400? or am I going fast enough at 200MHz? can anyone explain? TIA Lefty Link to comment Share on other sites More sharing options...
Wired Posted November 22, 2005 Share Posted November 22, 2005 Your CPU's memory controller is causing it to drop to 333 Mhz when running more than 2 sticks. That's BY DESIGN. Could try setting it back up, but it may not work. Also, can't find an Asus K8N SLI board on the ASUS website. Link to comment Share on other sites More sharing options...
leftorium Posted November 22, 2005 Author Share Posted November 22, 2005 that would be because they don't do an K8n 8-) reading too many posts - I have an A8n SLi of course 8-) at 400 MHz it refuses to boot - am i best manually altering to 333MHz 2.3.3.6.1T should I be pushing this as high as i can ? or altering the other memory settings to balance memory clock against latency etc maybe trying 400 MHz 2.5.3.3.6 or 2T ??? as I said - it's my first foray into this area - essentially i don't want to be running a porsche with citroen 2cv wheels 8-) I've also disabled the 4Gb support as I've got 4 sticks but only 2Gb Lefty Link to comment Share on other sites More sharing options...
Wired Posted November 22, 2005 Share Posted November 22, 2005 http://houseofhelp.com/v2/profile.php?do=extra Please update your system profile using the link above. TwinX1024-3200C2 are only guaranteed @ 2-3-3-6-1T with one or 2 sticks, not 4. If you just got the sticks, and want 2 GB, I'd try to swap them with the retailer for TwinX2048-3200C2.

RJLeong65 Posted November 22, 2005 Share Posted November 22, 2005 Most Socket 939 A64 3200+ processors in existence are of the Newcastle and Winchester cores. Venice-core 3200+ processors have only gotten on the market within the past few months. The memory controller in the older cores have trouble running all four sticks stably at DDR400, even with a 2T command rate setting. The newer Venice core can run all four sticks at DDR400, but still requires a 2T command rate setting. Link to comment Share on other sites More sharing options...
leftorium Posted November 22, 2005 Author Share Posted November 22, 2005 that sounds like a venice core CPU would be a logical upgrade? please say yes :biggrin: Link to comment Share on other sites More sharing options...

RJLeong65 Posted November 22, 2005 Share Posted November 22, 2005 Compare the cost of the restocking fee + new memory - old memory versus getting a new cpu. In this particular case (with a lower-end A64 CPU), the restocking fee + new memory - old memory may actually cost him more money than just getting a new CPU. Most resellers will charge a 15 percent restocking fee - and if the original memory costs him $120 to begin with, a 15% restocking fee will amount to $18.00, That's on top of the amount required for the purchase of a TwinX2048 kit (about $250). Compare that to the $160 cost for a new Venice-core 3200+. Thus: $250 + $18.00 - $120.00 = 148.00, plus he will have to pay for return shipping as well. As a result, the costs between the two choices (replacement memory versus a new CPU) are practically equal to each other. However, if a reseller requires overnight return shipping because they count only the time between they shipped out the memory and the time that they received it back as within the return policy (meaning that they must actually receive the old memory before the return policy period expires), then buying a new version of the same CPU will actually come out cheaper.

leftorium Posted November 22, 2005 Author Share Posted November 22, 2005 that's pretty much the position - I can get a 3500+ for about £120 if this allows me to use all 4 sticks at 400MHz then that's going to be my best option - the first 2 sticks are well out of it - had them for 6 months - the second pair would cost me £30 to restock £15 min per item and then I'd have to buy a 2048 matched pair at £160+ and have a spare 1024 matched pair as paperweights - if the 3500+ Venice will allow me to run the 4 sticks at a reasonable speed then that would be the best option - whats the recommended settings for my A8n + 3500+ venice and the 4 sticks? at the moment I'm running 3200+ winchester with 2Gbytes RAM dual channel (2 x 2x 512Mbytes matched) @2.7v 333MHz at 2.3.3.6 2T which seems stable - I'll prolly hang on and see how that fairs - it's running pretty well at the mo (touch wood) and benchmarks higher than comparable PC3200 rigs in everest thanks for the help guys - great bunch of people - in the home straight I think interesting thread on 1T v 2T here : http://forums.anandtech.com/messageview.aspx?catid=28&threadid=1577496&enterthread=y Link to comment Share on other sites More sharing options...
