Hi,

I recently bought a Corsair Vengeance 8gb 1600mhz RAM and plugged it in the motherboard, works fine but when I ran the Memtest+86 to check my RAM it says that the frequency is running at 1300 mhz. Checked my motherboard compatability and it says that it is compatible with PC3 12800 rams. So i was wondering why there is no ram section on my bios? is it possible that bios is locked. Bios is American Megatrends Inc. P01-A2. Desktop Model Number is Gateway DX4860-UB21P. Would appreciate any advices or feedback guys. Thank you so much.

most if not all consumer machines from big companies come with locked bios because they don't use quality/high end motherboards in their builds.

Welcome to Tom's Forum! :) 

This is a fairly universal 'issue' that most OEM PC's lock-out any form of OC'ing including DRAM Frequency. A few OEM PC's like Dell's Alienware allow it on some of their lines.

The difference between Defaults (DDR3-1333) and Rated (DDR3-1600) is very very small. This article should make you feel better - http://www.bit-tech.net/hardware/memory/2011/01/11/the-...

Hmm...it's not a quality issue for RAM frequency, it's done to prevent consumer originated problems. Gateway and others simply don't want RMA's or Technical calls from failed OC's. OEM products are built on 'reference' design.

true, but what I was trying to say is, even if said OEM didn't lock the bios, they use cheap mobos which don't offer a lot of features in the first place. Like you'll never find a locked asrock Z77 board in a dell desktop, it's most likely h61 from foxconn or similar.

Thank you for your insight Sir Jaquith, it was just so naive of me to buy a commercial desktop if I'm gonna end up modding the hardware of it. Well the only option is buying a motherboard. I know this is out of the topic but what kind of motherboard would be good enough to fit a Cooler Master Hyper 212 Evo with proper distance from
the Ram also one that can SLI and have ports for SSD.

It depends on the room you have in your case, most OEM MOBO's are mATX (H & W 9.6 in (244 mm)) and don't have the room for a standard ATX (H 12 in (305 mm) x W 9.6 in (244 mm)) MOBO. The CM Hyper 212 can have it's fan on either side and or moved if necessary so any LGA 1155 MOBO can work.

You have a few chipset choices of LGA 1155 MOBO's 'IF' you had a SB/IB (K) CPU, but keep in mind you cannot OC an Intel Core i5-2300 CPU. To OC you'd need a SB or IB (K) CPU -- SB: i5-2500K, i7-2600K, or i7-2700K ; IB: i5-3570K or i7-3770K.

Newest Intel chipset mATX (Z77) - http://www.newegg.com/Product/ProductList.aspx?Submit=E...

The only LGA 1155 chipsets that allow CPU OC: P67, Z68, Z77.

I have an cooler master haf 912 case so I think fitting of the motherboard is no problem. Might OC a little so I'm looking at i5-2500k Unlocked or i5-3570k Unlocked. I would like to go for Full ATX size motherboard. Can you recommend some for Z68 and Z77 Chipsets? Thank you will appreciate any replies.

I like the ASUS SABERTOOTH Z77 (great OC'er & 5 year warranty), or ASUS P8Z77-V or ASUS P8Z77-V PRO.

The P8Z77-V LE is fine if you're not looking at an excessive OC or any non-K, but it's not so fine if you decide to OC a (K) CPU and want +15% or higher OC. The ASRock Z77 Extreme4 should be a consideration for a budget OC'ing MOBO.

How high can you OC a (K) CPU on Asus Z77 Extreme 4?

The question isn't how high the OC it's at what vCore that limits the OC. Depending on your cooling solution 4.2GHz maybe a little higher i.e. (+15%).

Sorry bout the last post it's Asrock Z77 extreme 4 i was pointing out. So can it manage oc around 4.2 ghz? Was planning to make Cooler Master Hyper 212 Evo as heatsink. May case is Haf 912 with 200mm front fan Stock fan that came eith the case I think it's 120mm on the rear and the side and another 200mm on top. Is that ample enough for cooling? Also habve a fan controller for all the fans.

Here's My Build So Far Please feel free to add Details:
Mobo: (Possibly) Asrock Z77 Extreme 4
CPU: (Possibly) Intel i5-3570k
Heatsink: (Possibly) Cooler Master Hyper 212 Evo
GPU: EVGA GeForce Gtx 560Ti
PSU: PC Cooling Silencer MKIII (Will this be enough wattage to overclock?)
Case: Cooler Master Haf 912
Fan Setup: 200mm Front & Top Fan, 120mm Stock fan Side and Rear
Fan Controller: NZXT Sentry 2
