Msi p55-gd80 RAM

Hi All,

Im new here so be gentle!

I'm looking to get some RAM for the P55-GD80 mobo and have been told the Ripjaw does really well for performance and price.

I've got my eyes on one of these sets listed here:

http://www.overclockers.co.uk/produ...1&catid=8&sortby=nameAsc&subid=1387&mfrid=245

or

any other suggestions!

Which would be best to go for? Will be running the intel i5 750 with this.

Any suggestions would be appreciated

Cheers!

OK - the memory dividers are set up in such a way that if you want over 200BCLK with decent memory performance you need RAM rated well over 1600MHz so I would suggest you go for this GeIL and then run the memory multiplier at 4 with 18x QPI and rein in the timings as hard as possible once the CPU BCLK determines the ultimate speed of your RAM.

eg. Lets say your CPU tops out at 220BCLK, that will be 4.4GHz and your RAM will be running at PC3 1320MHz (3x Multi), PC3 1760MHz (4x Multi) or PC3 2200MHz (5x Multi).

So the answer, as I see it, is to buy the PC3 17000 RAM that will run stock at 2000MHz CAS9, and let it run at 1760MHz but at CAS7 (if you're lucky) or CAS8.

Does that make sense?

Welcome

Yeah, wont go far wrong with some G.Skill Ripjaw.

This imo is the best for price/performance ratio.

The problem with that RAM is that it doesn't clock high enough to support the required memory divider range so he'll end up running it like it was 1333MHz RAM, and it will cause the OC Genie to give him a carp auto-clock if he chooses to go down that route.

You need at least PC16000 RAM with these motherboards to make sure it's not the RAM holding back your overclock.

Lolll you've totally lost me!

Lets say that I overclock using OCGenie and not manually (i.e changing settings on BIOS), would the GeIL still be the best one to go or shall I go for the G.Skill 2000mhz (or 1600mhz with lower timings)?

Sorry for making it sound long winded! I just really dont wanna have to regret any purchase I make for this PC im building and then having the headache of returning/reordering etc.

Thanks in advance!

Right - you basically want RAM that will run at 2000MHz - so;

G.Skill Ripjaw at £78.99

or GeIL at £74.98

I'm still suggesting the GeIL. It's slightly cheaper, slightly faster and it doesn't look like it was attacked with a hacksaw.

Simon D · 27 Sep 2009 at 09:19

I would go with the Geil as well.

Tolmekian · 27 Sep 2009 at 16:52

The Geil is a great piece of kit, look's a lot better then the advertisement aswell, none of them awful looking stickers all over the place. I'd get it over the ripjaw and it's on TWO with £10 off atm

Thanks guys!

I've ended up buying the GeIL RAM over the G.Skill.

Cant wait to set it all up and get it running!

Thanks again!

Guys 1 more quick question..sorry to sound like a clueless noob but will this be compatible with my msi p55-gd80 AND my intel i5 750? someone told me my processor may not be fast enough?! :confused:

They're talking rubbish, you'll be fine

WJA, how does the baseclock affect the RAM differently to how overclocking the FSB does on older sockets? I've just ordered the G.Skill C7 (wanted the low latencies!), and am worried now!

Does overclocking a 1156 chip work in the same way as clocking a 775, with the BCLK replacing the FSB? If so, surely if you want a BCLK of over 200, while running the RAM at 1600mhz or under you can surely just change the timings...or can't you do that on a 1156 board?

Sorry for the hijack OP

Hey guys,I've just been reading this post,i'm changing my MB from Asrock P55Pro to MSI P55-GD80,but i still have the XMS3 1333 2X2GB,how will i fair with this,new to Overclocking and also my first build.

pearltoothed · 13 Apr 2010 at 07:09

Confused!

Corsair Memory 4GB (2X2GB KIT) DDR3 1333MHZ 240PIN DIMM
(MPN: TW3X4G1333C9DHX)
This is the one i have at moment, voltage is 1.5V in Scan but 1.5 to 1.65V in Overclockers -Corsair Memory 4GB (2X2GB KIT) DDR3 1333MHZ 240PIN DIMM (MPN: TW3X4G1333C9DHX) , a bit confusing, i'm worried,will i have to sell this and get new Ram. :confused:
