Memory upgrade in Gigabyte P55 UD4p

[mantech]

Hello,
I want to upgrade my gigabyte board (P55 UD4p) to 6 or 8GB. The cpu I have is Intel core i5 750. Can I populate all slot or need to use two slots with two memory dimm four(4GB) each. I have no idea of how to go about it.

Welcome back!

GA-P55-UD4P - http://www.gigabyte.com/products/product-page.aspx?pid=3160#sp
4 x 1.5V DDR3 DIMM sockets supporting up to 16 GB of system memory
Dual channel memory architecture
Support for DDR3 2200/1600/1333/1066/800 MHz memory modules
Support for non-ECC memory modules
Support for Extreme Memory Profile (XMP) memory modules

Assuming that you have no RAM, then 'ideally' a 2X4GB is best. Dual Channel is faster than Quad Channel, and if you need to go to 16GB then you'll have some expansion vs replacing all your RAM.

Technical Support / The CMP8GX3M2A1600C9 should be fully compatible with the P7P55D motherboard. Many of our 4GB module kits are fairly new and have not yet made it to our memory configurator, but these parts are definitely tested to run on the P55 chipset. / 11/5/2010 7:40:21 PM

Mixing is another 'issue' all together, and the Speed, CAS timings, Voltage and Type {including chips/side} makes it a lot more complex. Also, you don't want to mix Corsairs with OCZ or anyone else; ideally just get an EXACT match to what you already have installed.

I need the EXACT part-number(s), and hopefully the OCZ is a match-set. The simplest is to either 'look' at the stickers on the RAM or use CPUz - http://www.cpuid.com/softwares/cpu-z.html

Thanks for sharing! I will stick with exact match but I saw 2x 4GB GeIL DDR3 (PC3-12800) for $159.00 which is tempting, anyway I will do more research on that brand before I make a decision to buy it, By the way I am also switching OS Vista Ultimate from 32bit to Window Profesional 64bit OEM.

try and keep two slots empty.
go for 8GB(4GBx2) 2 sticks in dual channel mode.

Yeah! Youre right I will go and keep the Dual configurationg by upgrading to (2x 4GB) totoling 8GB, Thanks!

Otherwise just get a second matched set of OCZ3OB1600LV2G {OCZ3OB1600LV4GK}. Amazon $86 http://www.amazon.com/OCZ-PC3-12800-Obsidian-Channel-OCZ3OB1600LV4GK/dp/B002H9XRVG/ref=sr_1_1?ie=UTF8&s=electronics&qid=1289677174&sr=8-1-catcorr

edit reference - http://www.ocztechnology.com/products/memory/ocz_pc3_12800_obsidian_4gb_low_voltage_dual_channel_kit
OCZ3OB1600LV2G - stick 2GB
OCZ3OB1600LV4GK - set 2X2GB

Yes, Dual Channel is better, but it is NOT worth tossing $86 in the garbage either. I would get the Corsair's CMP8GX3M2A1600C9 way before GEIL!

Top RAM: 1. Corsair, 2. G.SKILL, 3. Mushkin, 4. Kingston, 5. Crucial -> but only for budget RAM.
