Show Us Your Rig [4]

Yes I enabled XMP in my bios so it it running 1600.

So I am at work, but have RAM that appears to be clocked at 1333 is there a guide or resource anywhere on what I can do to get this up to 1600?

System isn't in my specs.

here are specs:
Case: Rosewill BLACKHAWK Gaming ATX Mid Tower Computer Case

Mobo: GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD

CPU: AMD FX-6200 Zambezi 3.8GHz (4.1GHz Turbo)
Heatsink: COOLER MASTER V8 RR-UV8-XBU1-GP 120mm Rifle CPU Cooler

RAM: Patriot Viper 3 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 15000)

GPU: SAPPHIRE Radeon HD 6850 1GB 256-bit GDDR5

PSU: OCZ ModXStream Pro 700W Modular

It would be options in the dram config in your Bios, Intel uses xmp but I think AMD might call it AMP. Either way check the bios, if it doesn't show AMP or XMP profiles you would have to manually set the timings.

I believe this is your Bios(shot below)

See if you can set the memory clock to 1600

Thanks Dude :) I haven't messed with it yet which is suprising for how long I have had this comp now...

will give that a shot tonight if I can

Yes most Ram is 1333. Even when we buy 1600 or whatever it's actually 1333 by JEDEC standard, the merely add the timings to the profile (xmp) and sell it as 1600.

Do you have a link to this info? I don't think that is correct.

It isn't.

Read this link of info from the MSI forums:

Memory Timings Explained

Then look at my ram from the CPU-Z shot




As you can see my RAM by JEDEC stand is actually 1333, however they loaded an XMP profile with memory timings for 1600.

So looking at this I bought RAM sold as 1600, that is actually overclocked 1333.

If I am wrong I apoligize for putting out bad info, but from what I see I am correct.

From your link.

As you can see, the ram shown was sold as DDR3 2133, but it can only run at 1333 and still be within JEDEC spec! Also, you can see that it's max rated bandwidth is 1333! So really it is overclocked DDR3 1333 sold as DDR3-2133! Currently, the highest rated memory available is 1866 but is almost impossible to find or afford if you do, almost everything you see available for purchase is 1333 or at most 1600!

What they are saying is that RAM that runs at a different frequency than the JEDEC standard is out of their specs. It does not mean all RAM is 1333. Also The max bandwidth in CPUz is the default BIOS RAM as determined by the SPD chip, it does not mean that is the highest frequency.

It is very wrong stating that 1866 is the highest rated memory. I have 2133 and 2800 is readily available. There are rumors of 3000 but I've not seen it yet.

As to RAM overclocking, anything higher than what BIOS/CPU combos support natively is considered overclocked, however it is actually setting RAM to its specs.

Yes I see your point. I was basing my info off JEDEC standards, it's a technicality so to say, my ram runs at 1600. I did not mean to cause confusion, but as my screenshot shows I have 1333 ram overclocked to 1600.

Another thing I will have to look into when i get home...

Thanks for the info on this guys. never really looked into that and got some really good info.

and sorry for derailing thread
