LucasGrillis Posted February 7, 2008 Share Posted February 7, 2008 CPU-Z (Memory Window) seems to indicate that my DRAM frequency is running at 666.6 MHz and not at 1333, which is where it is set in bios. If I set it to the 1600MHz setting in bios the computer won't start. I also have left the reference frequency in the bios at Default. Should that change? FSB:DRAM is 1:2 cas latency=9 Ras# to Cas# Delay=9 Ras Precharge=9 Cycle time=24 Voltage=1.78 Command Rate 2T CPU-Z (SPD Window) indicates max bandwidth PC3-10700H (667MHz) I can upload screenshots of CPU-Z and bios settings if it will help. I have been trying to figure this out for a month now and would REALLY appreciate some help. I know it is some thing I am overlooking...

Corsair Employees RAM GUY Posted February 8, 2008 Corsair Employees Share Posted February 8, 2008 The is correct because it is double data rate 667 MHz x 2 = DDR1333. Link to comment Share on other sites More sharing options...
LucasGrillis Posted February 8, 2008 Author Share Posted February 8, 2008 Thanks for the info! My other question is...Will this memory not run at the 1600MHz setting? The bios have the XMP memory pofile, but for some reason it didn't want to run on those settings. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 8, 2008 Corsair Employees Share Posted February 8, 2008 The CPU would have to over clock to 400 Mhz 1600 FSB and I am not sure that CPU will do that. Link to comment Share on other sites More sharing options...
LucasGrillis Posted February 8, 2008 Author Share Posted February 8, 2008 There is a setting in the bios in the performance window for "Reference Frequency" which has 133, 200, 266, 333 and 400MHz option. (It is set now on default) I've never overclocked, but I'm assuming this is the place to set the 400MHz for higher processor speeds...Would the XMP profile then work? Would I have to change the cas latency, Ras# to Cas# Delay, Ras Precharge, and Cycle time to 7-7-7-20 as well? I'm assuming voltage too... Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 8, 2008 Corsair Employees Share Posted February 8, 2008 The CPU would have to over clock to 400 Mhz Clock Speed 1600 FSB to run the memory at DDR1600. I would ask Intel about that setting as I have not seen the Intel MB sorry! Link to comment Share on other sites More sharing options...
LucasGrillis Posted February 10, 2008 Author Share Posted February 10, 2008 I sent Intel Tech support an e-mail with that question two weeks ago, and a screen-shot of the bios asking for more information since bios terminology seems to vary a little from manufacturer to manufacturer. Never heard back. The multiplier and frequency settings in the biios act as if they can be changed by switching from auto to manual, but then you can't make the corresponding change. This is one of the Extreme series processors that is supposed to be able to be overclocked...That's why I bought it. Anyone know how to make it happen?

Xtreeme Posted February 10, 2008 Share Posted February 10, 2008 Intel wont write back, in the past I found their support to be worse then useless. Practically non-existant is more like it! Yes that cpu should be able to overclock to that easy.The big problem isnt its a intel chipset.....its a intel motherboard. They didnt allow oclocking on intel brand boards in the past. Do they now? I mean have the options for it even. Sorry you might have to read on google about that board to find out. Search for "Intel DX38BT overclocking" and after that "intel 775 overclocking". Read up on it first. Also note oclocking that cpu voids its warrenty, probably the boards too since its intel brand mainboard.:[pouts: Link to comment Share on other sites More sharing options...
LucasGrillis Posted February 10, 2008 Author Share Posted February 10, 2008 Bingo! I took your suggestion and looked at the review from XBit labs. I find it reassuring now to know that it hasn't been my inability to find the correct settings, but that the bios/motherboard combination is totally inadequate and possibly defective. I think that's why Intel doesn't want to respond, because they know there's a problem. I am now looking to replace this motherboard with an Asus, which is what I've built with in the past. Thanks to everyone and this forum for the help! VERY PROFESSIONAL Link to comment Share on other sites More sharing options...

LucasGrillis Posted February 16, 2008 Author Share Posted February 16, 2008 Got the new Asus Maximus Extreme motherboard in yesterday! I've actually got a manual in my hands, which is going to be a GREAT help... Intel needs to do the same! The Asus manual says that less than 3 gig of ram is recommended, though. I have been trying to figure this issue out for 2 months. I was planning to rebuild the system with the components I have but I am now rethinking this after looking at the forum posts. What would the ideal memory solution be for a moderate overclocking? Does anyone know if going to Xp 64 bit and more ram would enhance Photoshop, Premiere and After Effects?

bsautner Posted May 4, 2008 Share Posted May 4, 2008 Thanks for the post that led me to the solution. I put a lot of $$ into building my ultimate pc and was getting very worried when i tried to up the RAM. Symptom - on my intel extreme DX38EBT MB i put 4 moduled of Corsair TWINX Dominator Dual Channel 2048MB PC14400 DDR3 1800MHz Memory totaling 8GB Ram. I'd pass all ram tests, system would boot but stop randomly, OS Installs would fail (both Linux and windows) random reboots during installs.... removed HW, ran tons of tests and went nuts on the problem Solution: The DX38EBT automatic settings for this ram config uses too low of a voltage. You need to go into the memory overide section of the bios setup and up the voltage, set user config ram settings and use the info from this thread http://www.asktheramguy.com/forums/showthread.php?t=54052 machine flying now, thanks!
