Memory not running at full speed

post #1 of 10
Thread Starter 
I recently built my first pc and everything seems to be working fine other than my memory. It's Patriot sector 5 (4gbx2) 1600 and when I check the memory in cpu-z it shows up as running at 535MHZ. It also shows up this way when i use the asus MB tools. I've tried to tweak configurations in the bios to make it run at 1600 but so far have had no luck.

I dont know what I am doing wrong. Please help. Thanks.

Also, If this is in the wrong section please let me know and I will delete.

edit: here is a screen shot. In that screen shot i just went with optimized default bios settings. Thats why the timings are at 7-7-7 20 as opposed to 9-9-9 24 recommended

The 533 is shows is half of the actual effective rate. So while it's running at 533MHz, what you should think of that as is 1066MHz.

Of course, that's still lower than what it should be, so you'll probably just have to manually adjust your memory settings in BIOS. If you manually set it to 1600, the timings should adjust to that automatically.

Just make sure what it shows in BIOS is your effective speed. It it's saying that it's 533 now, you definitely don't want to change that to 1600. In that case, 800.

Edit: Sorry, I can't read. I missed the mention that you already tried to change it. Are you definitely saving it there? There's no reason for it not to work.

Edit edit: Also, do you have XMP enabled?

Well I'm still kind of getting used to the new bios the newer MB's have but I've tried using manual settings and putting in the dram voltage along with the 9-9-9 24 timings and it always reverts back to some slower frequency. I think the highest I have ever got was 667MHZ.

I thought I had XMP enabled on one of my boots and I dont think it worked. Although, this is my first build so I could also be entirely wrong.

Tweaked some things back 9-9-9-24 at 1.5 as per specs from manufacture. It looks like it works but i still dont understand why it says that I have a max bandwidth of 533 mhz. I'm a noob though so maybe everything is fine

It reverts in your BIOS UEFI settings, too? If you manually set the frequency, voltage, and timings, and it acknowledges them and the new 1600 speed there, I can't imagine why it wouldn't retain that. Is it booting up just fine after that? Just in case it's a situation where it's failing to boot and reverting to the old settings automatically. And are other changes you make there being retained?

If it stayed on 667 once, then there may be a chance that it's just failing to boot any higher. Though I don't know if that motherboard will automatically recover settings. I know some Gigabyte motherboards will, but not sure about Asus.

Also, what's the DRAM voltage at now? The memory's rated for 1.65v, but your motherboard's made for 1.5v. I don't know if it would, but it may be running it at 1.5v when that's not enough for it.

I could be mistaken, but looking at those screens, I'm assuming the only way to automatically set 1600 is with XMP. Otherwise, the JEDEC profiles only go up to 533. It could be the voltage thing, too. If it was defaulting to 1.5 for any reason, it may be setting frequency to 533 to fit that.

Whatever the case, it's definitely running at 1600 now, so it should be good. If you manually set the voltage to 1.5, then you may need to raise it if it gets unstable for any reason. I'm not entirely sure whether it'll be fine at 1.5 or not. If it is, that's fine. But as I've heard, 1.65 is okay on Sandy Bridge motherboards, too.

Thanks for the help man. I wish i could give you more info but im not entirely sure what the problem is either. Im also still a bit confused on max bandwidth and frequency and how those work.

I thought i had the system stable at 1600mhz with 9-9-9 24 but after i shut the pc down and came back to it later it wouldnt boot. I have it at 8-8-8 20 1333mhz right now and it seems to be stable. ( i think at 1.5 v)

I guess i should just be happy with that

I have the exact same problem.


I can only get them to run 1600mhz cl9 or 1333mhz cl7.. while they are set to 1600mhz cl7 1.35v as stock.. i tried everything

I think I have the same problem as u guys. http://www.overclock.net/intel-memor...ock-speed.html

If anyone find a solution please let me know. I can run my RAM 1866Mhz. It keeps running at 1600MHz. I tried to run 1333Mhz, but bios and cpuz still showing 1600Mhz. The bios saved other setting like CPU clocks, but it looks like it's not saving RAM setting.

Update: I just reflash the bios from 1053 beta back to 1003 and got the manual setting and XMP profile working again. I think it might a bios bug. The 1053 beta added "Internal PLL Overvoltage" for D2 chip, but I might just wait till it's out of beta.
