RAM upgrade help on current build

HomeGrownHeroz · Mar 13, 2014

I've recently started upgrading my PC, most parts of which are now getting on a bit. Last week I upgraded my GFX card to a GTX 770 but am now wanting to upgrade my RAM.

I've been looking at these two in particular as they seem quite good vs. price but I'm open to any suggestions and advice on what I should be aiming at.

One thing I've noticed is this XMP profile, which I don't think my motherboard supports. Should I wait a while to upgrade the RAM along with CPU and new motherboard so that I get parts that definately all work together?

Below is my current build.

Kingston 4GB (2x2GB) DDR3 1333MHz HyperX Memory Kit CL7 1.7V
Samsung HD103SJ Spinpoint F3 1TB Hard Drive SATAII 7200rpm 32MB Cache
AMD Phenom II X4 840 Socket AM3 3.2GHz 2MB Cache Retail Boxed Processor
Asus M4A79XTD EVO Motherboard
Antec 300 Three Hundred Case
Antec TruePower New 650W Modular PSU
Gigabyte GTX 770 OC 2GB GDDR5 7000MHz Dual-DVI HDMI Displayport PCI-E Graphics Card
Samsung SH-S223 22x DVD±RW DL SATA Optical Drive
3 x Corsair AF120 LED Blue Quiet Edition High Airflow 120mm Fan Twin Pack

Any help will be greatly appreciated.

The Hyper -X is the better choice.
It is Cas9 instead of the Corsair Cas10.
The XMP profile can be manually set in the BIOS on AMD boards. Some AMD boards do offer XMP support but is is up to the manufacturer to implement it properly.

OK cool. But what's the actual difference between cas9 and cas10?

Unolocogringo · Mar 13, 2014

Simple answer to keep it understandable.
Ram is rated in wait cycles between access commands. Memory is structured in colums and rows.

A memory read is sent. The controller issues a command to active a certain column. It then must wait to issue the command to access the row. It must then wait again to issue another column or row access command.
The hyper-x has a wait time of 9 cycles between commands. The corsair has a wait time of 10 cycles between commands.
So theoretically the hyper-x memory would achieve 10% more memory access comands resulting in arround 5% better memory performance in memory intensive tasks.

Ah sweet I get ya. So good purchase? And work well with current build and motherboard?

Be prepared to drop the freq to 1333 if needed, of the Phenoms the 965 (rev 3C) was the first that could reliably run 1600 sticks, the CPU line itself is rated up to 1333

I personally think its a good purchase.

Tradesman1 :

OK, cheers for that. From the looks then my CPU cant support any more than 1066. Is that correct? Is it worth still purchasing this, even if my rig won't get the most out of it until I next upgrade?

Also just to clarify, Is this even compatible with my build because I couldn't see my motherboard listed in the compatible section on PC part picker.

Bump?

Tradesman1 · Mar 16, 2014

I think I'd look to a 1333 set for this
