Hey was looking for the best choice of RAM for the EVGA 780i?

533MHz DDR2
667MHz DDR2
800MHz DDR2
1200MHz DDR2

those were the frequencies it supports.

Btw i am not an expert at RAM selection so any advice is welcome.

What processor will you be using? Will you overclock? What do you do with your computer? How much do you plan to have? 1GB? 8GB?

I am considering purchasing this board. If I answer those questions, could I hijack this thread for a few and get a few recommendations from you guys?

If it was an eVGA 780i mobo with a 45nm quad core (QX9650), 4GB of RAM preferably in 2x 2GB. Want do some SLIGHT overclocking without upping voltages. Machine must remain stable. Machine to be 30-40% gaming, 20% video watching, rest "normal" use of email/web browsing/some programming/some web site work/Word/etc. Note: using a very high res. monitor (30").

boonality posted while I was typing. JEDEC is the governing body which sets standards for memory and their current top speed for DDR2 is 800@1.8v. Most memory manufacturers sell their RAM at it's overclocked rating, take this for example http://www.newegg.com/Product/Product.aspx?Item=N82E168..., it is DDR2 1066 5-5-5-15 2.2v while it's actual JEDEC specification is more likely DDR2 800 4-4-4-12 1.8v or something along those lines.

What does all this mean? You can buy some quality DDR2 800 and relax the timings and increase the voltage and will likely be able to reach the same speed of the higher prices RAM but it's not guaranteed. Also when your looking for RAM don't just look at the speed but also the timings and voltage needed to reach that speed.
Take this for example
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It is rated at DDR2 800 5-5-5-18 1.8v while this
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Is rated for DDR2 800 4-4-4-12 2.2v
At first the Crucial might look like the better option due to it's lower timings but when you look at the voltage the Crucial is sold at it's overclocked speed and is pretty much maxed out while the A-Data should have some headroom and will likely be able to achieve faster speeds and or lower timings.

lol theif hmmm amazing i using the same specs as Waspy
my CPU is qx9650
4 to 8 gigs of ram
want overclocking as a possiblity
its for hardcore gaming,movies and intense processes
March 11, 2008 1:26:10 PM

Good info. *Goes back to reconsider memory choice for new computer*

Eh?

:D 

Some good quality DDR2 800 should suffice as the best option. I belive I'm going to choose DDR2 1066 but I keep computers for 6+ years before I "upgrade". Which consists of donating it and building another.
March 11, 2008 1:34:20 PM

lol rightttttt

yeah so what ram u recommend ??
and why was the CPU so important.
March 11, 2008 1:35:38 PM

I would suggest somthing like this http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It has good timings, 5-5-5-15 @1.8v, which you can likely get to about 4-4-4-10 with a slight voltage increase and with an Extreme CPU you won't be needing super high FSB speeds since you can adjust the multiplier for overclocking. A FSB increase to 1600 wil run 1:1 with DDR2 800 which should make these modules perfect for your system.
March 11, 2008 1:41:14 PM

sweet any other options not that i have a problem with AUsch30 suggestion i just want to look at a few and make a choice.
March 11, 2008 1:45:38 PM

Another thing to consider is the fact that the 780i just as the 680i has an issue with high FSB speeds with quad core CPU's so keeping the FSB relatively low while increasing the multiplier should give you the best overclocking results. Intel chipsets don't have this issue which is why they are a better option for overclocking non-extreme CPU's. If you were using a non-extreme CPU on an Intel board you would be looking for something that could run in the 1066 or so range to run along with a 500+ FSB but since you best option would be to keep the FSB fairly low you should get something around DDR2 800 with low timings.
March 11, 2008 2:06:29 PM

thx a bill
March 11, 2008 2:52:52 PM

ok well i will go with that ram cause it looks to good to be true extra cheap and 4 gigs.
btw can u explain what the fsb's relation to the CPU.
March 11, 2008 3:20:33 PM

I would be aware of that G.SKILL memory on an NVIDIA board. Read the reviews. It seems the stuff works fine on intel chipset boards but not NVIDIA... seems really wierd to me but i wouldn't want the hassle.
March 11, 2008 3:48:37 PM

ok so this means i would encounter problems ?? any solutions??
March 11, 2008 3:50:53 PM

You might not, I was just saying that after reading the reviews, people with 780i chipsets were coming forth with issues with that memory. You can always do what's recommended by buying the memory that is listed in the QVL of your motherboard.
March 11, 2008 6:55:25 PM

Is there another name brand, say Corsair, which would be a good choice as well?
March 11, 2008 7:24:35 PM

yeah what waspy said
March 11, 2008 8:01:49 PM

I looked through the reviews of the RAM I suggested and there were several P35's and a few X38's and 680i's and none of them listed any issue at all with compatibility. I agree that Nvidia and more specifically Asus has had issues with memory but the G.Skill seems pretty good. It's also a good idea to check out the QVL but just remember that companies don't have the time or resources to test every stick of RAM available with every board.
March 11, 2008 8:11:11 PM

ok curious where will i find the QVL list ??
March 11, 2008 8:12:41 PM

My only suggestion would be to check the voltages of the ram you might buy vs the voltage of the memory in the QVL and you should be ok

I've got 4gb (2 x 2gb) of DDR2 800 OCZ Vista Performance Platinum running at 888mzh 5-4-4-15 and 2.1v. http://www.memoryexpress.com/Products/PID-MX19221(ME).aspx
$80 is hard to beat. It's totally stable, and passes every torture test i could find. best part is even though it's at 2.1v that's a factory rated over volt so it's warranty's still good. i got it down as far as 3-4-4-12 at 2.15V but it wasn't very stable... i think since i've got it overclocked it's at it's limit at it's stock latency timings.
Just my two cents, but it's an unbeatable price and pretty smokin fast performance.

I've been trying to do some research on this Corsair memory and it seems to be very nice. It's a little more expensive than others but with the rebate it's only $99. It has nice timings of 4-4-4-12 at only 2.1V I see a lot of RAM has these timings at 2.2V. I'm trying to find out some info on how they overclock. Either way, 4-4-4-12 at 2.1V at 800MHz is nice :sol: 
March 12, 2008 3:57:11 PM

I just upgraded to a Q6600 and built one for my Nephew as well with the same processor and I put 2x1GB of Corsair Dominator PC8500 in his and 2x2GB of OCZ Reaper PC8000 in mine, both seem to work well. I bought the OCZ because I got a good deal on it, I've owned several models of ram from them and they have all been great. Not to mention overclocking does not void the warranty; OCZ is very overclocker friendly. When you decide on a speed then try to buy the brand with the tightest timings, the lower the better like 4-4-4-12. An excellent DDR800 is Corsair PC6400C4 make sure it's the C4 version, I used it in my my wife's system and it's fast and stable. Corsair, OCZ, Mushkin, and Crucial are all top quality brands. For good budget brands: Patriot, G skills, Geil are all good quality budget brands. Which ever you decide it's best to check your motherboard's website to see if it has been certified to work with it. Most times it will work anyway but at least if you buy something on the list then it will definitely work.

No, SLI ready doesn't really mean much it's just a way for them to get more money out of you.
March 12, 2008 10:45:44 PM

The G.Skill 2x2 GB DDR2-800 on newegg is probably your best bet. It stays cool, and 2x2 is usually more stable then 4x1 or 4x2 would be. And of course its good that it's cheap. What operating system will you be using? 32 or 64 bit? It will make a difference with the memory limitation on 32 bit!
March 13, 2008 12:29:05 AM

most likely windows vista but as for 64 bit or 32 bit i am not sure which one should i chose ?
haven't thought about operating system yet sue me i am finding out new stuff the more i am on this forum
( gonna be using the qx9650 btw)
March 13, 2008 12:02:02 PM

If you are doing Vista, go 64bit. If you are going XP, never TOUCH the 64bit and stick with 32bit.
March 13, 2008 12:42:07 PM

March 13, 2008 1:22:32 PM

next few questions whats the symptoms of unstable ram?

I am currently looking at buying the G.Skill 2x2gb but anyone have any recommendations from Crucial and corsair
for 2x2gb ddr2-800?
March 13, 2008 1:33:44 PM

Check out CRH's recent thread, it basically hits all the same points. He ends up looking at some Corsair stuff. I must admit, I'm considering it heavily as well. Good times, lots of Newegg reviews on it that are good, and a name brand which is considered better, in general, than G.Skill.
March 14, 2008 12:21:28 AM

ok well guess what i am from the caribbean and newegg does not ship to the caribbean so anyone knows any quality sites that ship the above recommended G Skill or Corsair or crucial RAM ?

Or recommend any really popular brand of 2x2gb RAM that will be availible on other sites like amazon or tigerdirect ?

EDIT:
To make a long story short which of these 2 is better

March 14, 2008 12:54:16 AM

Caribbean? Dude let me crash at your place for a bit and I'll hand-carry some RAM down there for ya!
March 14, 2008 3:24:33 PM

ok making an even simpler choice which is better

4GB Kit (2 x 2GB) PC2-6400 DDR2 Reaper Dual Channel 800MHz 4-4-4-15 Heatpipe heatspreader

DDR2 PC2-6400 Reaper X HPC Enhanced Bandwidth 4GB Kit (2 x 2GB) Dual Channel; EPP 4-4-3-15, 2.1 Volts

and i'll even throw in that walking along the sea in Trinidad is nice.
( which has nothing to do with RAM but i thought it would catch your eye)
March 14, 2008 5:29:35 PM

hey, sorry to but in on this thread but i have some what of the same problem. I have the Evga 780i board with the new Wolfdale processor 3.0ghz.
Well last week my ram died, and i wana get some quality ram.
I had my cpu oc'ed to 3.6 and my fsb was 1600mhz, and my ram at 800mhz (standard was 667) so did my ocing kill it it? i know but i want some ram that will take the pressures of ocing.

i had all i have ever had is corsair, so i realy dont have experience with other brands
i am lookin' at 1066 ram (2x2gig modules or 4gigs total)
but again am not sure

What PSU do you have? It could be that the RAM is only the first to go.
March 17, 2008 4:37:12 PM

i have a 750watt psu, not sure on what brand it is though, I have been think of getting a 850 for sli, and that the fact my old one is very noisy, like 30dbs, it's crazy loud!

how does that effect my ram besides over voltage?

R u saying that my psu could be frying my stuff, and i should get a new one?
Works for me, but not sure on a brand (a quite one!)


thx

Lower quality PSU's use cheaper components which don't provide the solid stable power of higher quality units. A lot of people after spending a bunch of money on other components buy the cheapest PSU they can find which is the worst thing you can do. List all your components, I would bet that even with SLI you wouldn't need a 850w unit. A high quality 650w or 750w PSU would be plenty to run just about any system. Some companies that make quality PSU's are Thermaltake, Corsair, FSP, Silverstone, Enermax, OCZ and the best PC Power and Cooling (owned by OCZ). Not all PSU's from these manufacturers are great but the all make great units so you need to look at the perticular lines within the company and find the quality ones (Ex. Thermaltake Toughpower is very good while the Purepower isn't)

I did this back when I was a newb...large PSU too, but crappy. Eventually started causing problems...the norm. stuff when you are running a junk PSU...hard drives shutting down, things clicking off, lock ups....

Got a nice Coolermaster PSU, never had those problems again.

For my new system I'm going with a 750W PCP&C Silencer! Good stuff.
