Hello all,

As I'm planning to build a system with an Asus M3A78 and an AMD Athlon X2 7750 (2.7, Dual Core, Black Edition), I would like to ask for some input about what memory I should use.

I plan on overclocking the processor but as it has an unlocked multiplier I understand I can simply overclock it by increasing the multiplier, without bothering about FSB speeds etc. This way it can, according to this review, get to ~3.2 GHz, stable, and without the need to mess with anything else.

So here's my question, I plan on running 2 GB of DDR2 RAM for the time being (2x1 GB, Dual Channel). Should I get a couple of 800 MHz sticks or prefer the 1066MHz ones? Price difference is roughtly $13 (KINGSTON KVR800D2N6 vs KINGSTON KHX8500D2K2/2G HYPERX 2GB)

Any help will be much appreciated. This is my first completely-from-scratch system build and I'd like to get things right :)


Thanks in advance.
 
I'm running 1066 with my 4gb of dual-channel unganged memory on a 7750.
My FSB: DRAM ratio is 3:4 at stock.
I usually like to run my RAM at DDR2 800 because the ratio is 1:2.
But I feel like it's faster at 1066 speeds.
I don't know what others will tell you but I feel like 1066 is just a little zippier for everything.
 
I searched a bit and there's some information here already.

I'm not sure, I tend to think 800 would be OK since I won't be bothering with the FSB frequency, plus it consumes less power (I believe so, at least). But on the other hand, 1066 could give nice headroom and may help if I get my hands on an AM3+ CPU down the line.....I'm lost :)
 
Yeah I got 1066 mostly because I'm planning to get a Phenom II in about a year or so.
Just wanted the 7750 because my old CPU was too slow for anything and I had the money at the time.
Another reason to go 1066 I guess
 
thanks for posting this, i was just looking around for the same info. i have my 7750 and 800, but can always switch up to 1066 and dump the 800 into another system here.

that was a good article, remember reading it earlier. but it doesn't really have an apples to apples comparison for amd systems running 1066 and 800.

I would caution you against jumping the gun on this. I've been helping a friend with a new AMD build recently, and just ran up against g.skill ram myself.

I do not know for certain (as I haven't really gotten a definitive response from a member here at [H] that was able to provide much of an explanation) - but from what I have been able to gather, G.Skill ram does not work in AMD mobo's.

If you are looking for 4GB of 1066 DDR2 Dual channel, I would recommend, this set of corsair ram. It's only about $5 more than the G.Skill, and besides, it's Corsair - I've had nothing but wonderful experiences with their products.

I have that exact set in my 6-month-old ASUS AM2+ build, and it works like a dream.

Hope you check back to see this in time.

Honestly, after I switched from Crucial to Corsair, I never went back. I've never used kingston, so I can't really give you first-hand advice there. From what I have heard though, their stuff is decent.

As for not doing MIR's... I had no way to know that when I recommended that one, nor can I fathom why you wouldn't want to take 5 minutes of time to save $15 and get a higher quality of ram for the same price as the other guys.
 
dem, its not that i wouldnt take time to submit the mir, its that people on both the corsair page and ocz page havent gotten the mir. so i dont trust them. i had corsair in the past and loved it. ill probably just get the corsair.

Very Odd...

I run 4 GB G skills DDR800 sets in both of my HTPCs using AMD 780s... Never had a problem with either.
 
i went with the g skill...did alot of googling research. that g skill got better remarks than the ocz and corsair, tho im sure both are nice.

That is very odd. I bought a corsair PSU, and that Dominator ram, and recieved both of my MIR's within the week.

As for the G.Skill, I hope that works out for you. Could you send me a PM with the results? Ty
 
Hey daytripper,

Thanks for the information. I finally went with the Kingston 800MHz as I did not wish to take any chances and initially I will only be overclocking mildly by simply adjusting the multiplier. I will consider an upgrade later down the road. Thankfully modern RAM isn't that expensive.
