the thing is, I can get pc-3500 for the same price! is pc-3500 just as capbable/compatible for overclocking when using the nf7-S v2 board? do i have to do something like underclock my ram to run at the same timing? sorry, I'm a little new to overclocking ram, but everyone tells me to get good ram. otherwise, the ram is the bottleneck when overclocking. thanks!

well the higher the FSB the RAM supports the better because you will have less of a chance of the RAM actually having a negative effect on your overclock. You want to be able to clock the RAM as high as possible because you can drop the multiplier on your processor and get better performance for the same megahertz. What I would do is find some good PC3500 RAM from brands like Corsair XMS, Kingston HyperX, or Mushkin Level2. You want something with good timings so you will get better performance also.. Hope this helps :)

Just buy Corsair XMS, Kingston HyperX or Muskin Level 1 (level 2 is no longer available:() All of those ram will do around 220mhz with tight timings, which is plenty for an Athlon, especially one with an adjustable multiplier.:D

ah, so it shouldn't really matter if i get pc-4200 ram? i just saw this great deal over in the hot deals forum. 1 GB of high quality pc-4200 for under 200 bucks!!! also, what do you mean about the timings? is that the 2-3-3 Cas latency? is that considered good? or is 2-3-2 better? thx in advance!

No guarantee's on memory speed... my Mushkin PC3500 Level 1 can't run it's rated 216 Mhz @ it's rated 2-3-3 timings... although that may be due to my power problems. We'll see today when my TruePower 430 arrives.

PC3200 RAM is fine... even with an older motherboard like mine (Asus A7N8X Deluxe Rev. 2 over a year old) you'll be able to get to 2.5 Ghz with no trouble... 200x12.5

^^ what power supply are you using? I have an antec 350W that came w/ my 3700BQE. is that enough power for OC'ing? Or is it worth it to get a 430W True power?

My Antec SL350 isn't cutting it with my CPU at 2.4 Ghz... look at my rig for the rest of the crap I have to see if you might have similar power requirements.

Hah, I was actually going to send you a PM the other day, telling you I thought that might be exactly why your Mushkin couldn't run at a higher voltage/better timings.:D

FedEx just pulled up!!! :D

Wow... not bad looking for a FedEx driver... she's new! Wonder if she'd be offended if I asked to take a picture of her. lol

myocardia: could ya share why you think the mushkin pc-3500 wasn't doin well? that's the ram i've been thinking about getting actually.

haha, i never see the fedex delivery person. by the time i get home from work, the packages are already delivered = )

Jeff7181 I have the same RAM as you do and I can't push past 215 either without big stability problems... Let me know if you figure it out because I would like to get my FSB up to 230 :) But I don't know if it's my motherboard holding me back or the RAM... do you know how to tell???

I bought 3500 to go with my barton 2500+ desktop, but since it can't even hit an FSB of 200 without serious ass cooling, my memory could have been 3200. If I was going with a mobile I'd definitely get above 3200 spec, since you'll want to return the damn thing if you can't hit 3200+ on the CPU at least.

Well, my new PSU seems to have helped... running 218 Mhz now @ 2-3-3-11.

I'm positive it's not my motherboard that's holding me back because for about 3 months last year I ran it at 221x10 with a RAM divider... and I was also able to run it at 233, again, with a RAM divider.

Jeff's it's just your vcore holding you back now, since you have a good stepping and a real psu. Everyone with a mobile 2500 that I've seen who's running it at 2.5 is using 1.75v vcore or slightly higher.

Temps get too high at that speed... 64 C at 2.5 Ghz on 1.725 volts.

beloved patriot, remember that this memory is nothing compared to the Mushkin Lvl 2 that was so awesome. The level 1 is slightly better than XMS or HyperX, if you have the ability to give the ram more than 2.8v. Mushkin is good ram, but it eats voltage for breakfast. Quite a few people give theirs 3.2v and higher, to get theirs to those high 1:1 overclocks they have. I say get it, if your motherboard supports raising the vdimm to at least 3.0v, and don't if it doesn't. BTW, it's too late now because I was taking a nap, but I thought the reason he couldn't get his ram any higher was that his psu didn't have enough power. I would recommend you get either XMS or HyperX if you have the money, and either Buffalo Tech. PC3200 or Kingmax PC3500. From what the people who've bought the Kingmax have said, it will run higher fsb's than the Mushkin PC3500 seems to be doing, unless the Mushkin has over 3.0v.

Dang, what are you using to cool it? You know, an 80mm fan, wire tied into the inside of the case where it's blowing across the heatsink can drop your temps considerably, no matter what heatsink you have. Well, I can't say so from experience, but the people who've done that claim at least 5C temp drops under load.

IS the kingmax really that good? I would be happy to run it at its rated speed.:)

Ummmm... I already have a fan on the heatsink, lol. That's the diode temp by the way... it seems as though a lot of people don't know how to set up their software to read the diode temp, so they report socket temps, which are almost 10 degrees C lower for me...

You have a heatsink fan? Or you have a secondary 80mm fan blowing across your heatsink (through it), toward the exhaust fan?

Lyfer, I haven't bought any of it yet, but I definitely have plans to do just that. The people who own it, including a couple on this forum, say that theirs runs high fsb's a 2-3-3-x at 2.8v, even though it's only guaranteed to do 2.5 CAS (the first number in ram timings, and most important by far). Didn't you read any of the newegg customer reviews on the link I provided?

I have a fan mounted on the heatsink.

Well, in case you're interested, Jeff, the people who have needed to do it say that it lowers their load temps by 5C or more. Hey, give it a try. If you already have a closet full of 80mm fans, like I do, then it won't cost you a thing to try. And I can't remember how you feel about noise, but since it's totally inside the case, an 80mm or 92mm fan even if it's running wide open at ~2500 rpm, isn't going to make any noticeable difference at all in acoustic output. I'd give it a shot, if I were you. Wire ties are cheap as hell, if you don't already have some, and it's completely reversible.

It also has to do with the TruePower 430 slowing down my case fans... my max case temp before was 22C, now it's 28C... so I think I'm going to plug the fans into a regular power connector and not use the fan only connector. It's noticeably quieter like this... but I don't care that much about the noise level. Hell, I've lived with it for over a year like it was before and never had a problem with it.

Very good idea. I never used mine, they got wire tied out of the way about 30 seconds after I got the last psu screw tightened!
