What will Crucial PC2700 overclock to?

Atm I've got Crucial PC2100 CL2.5 which goes upto 152MHz CAS 2-2-2-6🙂.

I'm getting Crucial PC2700 & an A7N8X soon ,what do you think the 2700 will run upto at CAS2?
 
Well some sticks will do better than others. Also, if you increas RAM voltage it will go higher (make sure you have good cooling). I would guess that you could get it to 180mhz at least.
 
Yup, I've run 180 fsb with 2-2-6-2-1 settings. Crucial PC2700 in 128meg sticks are a setifarm overclockers dream come true.:Q Reasonably fast, and dirt cheap.... 😉

I used 2700 Crucial with my P4PE/L and ran it@SPD timings only, but it did run 403DDR@2.6v solid and stable! I hoipe you get some as good as what I had WU's WU's WU's!!! 😀
 
I'm using two 256MB sticks of Crucial PC2700 on an Asus A7N8X Deluxe.

Running stable at 198MHz, CAS2.5 7-3-3, 2.8V.
 
Had 2 sticks of 256MB...tested up to 180 from each (Iwill 333) then when I put them together they only went 168FSB so I kept one and traded off the other...doing 175 Cas2 on the Iwill with 1 stick...Daughters Puter and I'm sure being 6 years old she could care less what the FSB is but she enjoyed helping put it together 😉
Edit= Link fixed
 
A newbie question:
what does each number denote?
CAS 2-2-2-6
CAS2.5 7-3-3

got a generic PC2100 running at 155FSB on a p4 2.4 (c1). Anything higher seems unstable and fails the Prime95 torture.

 
uh oh! ,you're asking us to remember!:Q😱😉

I had to look at the manual!😛

2-2.5 CAS Latency
2-3 RAS precharge time
2-3 RAS to CAS delay
5-6 Active to Precharge time

Not sure where the 7 comes from!😕

Nice!:Q
What does it max out at if you set 2-2-2-6?

I'd be happy with CAS2 at 175MHz ,btw your linked is messed up ,1 too many http's😉
Nicely painted btw but what a gross colour!😛
What paint did you use for the plastic?


Anyone else with results?

HEY HEY hey hey...that's my 6 old daughters favorite color Barbie Pink with Passion Purple as her next best...Link fixed and good luck on the RAM and we use Automotive PPG paint with over a 5 step process...

Edit= More info 😉

Hey Led, how've been buddy? 🙂 That's pretty awesome paint job!! One thing though... Isn't that case kind of big for a 6-year old? How is she going to carry that to her lan parties... 😀😉😀
 
Thanks Good Max and you?...Aja (Daughter) made me remove the Zen CDROM to replace it with a DVD so she could watch the likes of H.Potter and Ice Age 😉...as far as Lan Parties go, we get the stuffs furnished 😉...she'll just Jump on the HD and we'll roll 😀...More Pics of our work can be seen @ CrazyPaint😎

Now that Pruple is much nicer🙂 ,though myself I would of gone for Metallic light blue😉

Hehhe...how about a Tricoat-Mirage?...Depending on the lighting ...it'll go Blue, Green, or Purplish-Red, BTA we can do any color and or design! 😎

Now that the adversments are done maybe we can continue the subject matter @ hand 😀

Hehe, thanks. 😀

I couldn't tell you what CAS2 maxes at, I haven't used it at all really. I knew the sticks wouldn't be able to handle CAS2 at the high FSB speeds I was aiming for so I only ever bothered with CAS2.5 and slower.

If it's any help, here's some of my findings that I recorded:
185MHz CAS2.5 6-2-2 2.7V - Stable
198MHz CAS2.5 7-3-3 2.8V - Stable
200MHz CAS2.5 8-3-3 2.8V - Unstable
200MHz CAS3 8-3-3 - Stable, not certain of voltage used
207MHz CAS3 8-3-3 2.6V - Very unstable, required repairing XP installation (woo!)
211MHz CAS3 9-4-4 2.8V - Very unstable
 
Thanks for that info🙂

I didn't think you could get CAS3 on DDR RAM?😕
Btw what's the 7 & 8 settings refer to?

Anyone else use Crucial PC2700?

Here's the memory timings available in the stock bios that came with my A7N8X:

SDRAM Active Precharge Delay: 1-15
SDRAM RAS to CAS Delay: 1-7
SDRAM RAS to Precharge Delay: 1-7
SDRAM CAS Latency: Auto, 2T, 2.5T, 3T

 
I know SFang and others have both run past 190MHz on their Crucial PC2100 with the nForce2's, and the A7N8X-Deluxe in particular. Granted, they may be blessed with lucky results, but I'd imagine Crucial PC2700 is almost certain to hit ~180MHz and probably far higher, given around 2.7-2.8 volts. In some cases the motherboard itself will probably blink first. Due to the low price of Crucial PC2700 right now, I decided to stock up, as you know 😀

In general I would steer you toward the EPoX 8RDA+ due to EPoX's responsiveness to the customers, lower price and maybe a slight edge in overclockability, statistically speaking. Plus the box has an X-Ray of a cheetah on it (and no one scandalize me by suggesting it's a dog again! :disgust: ). The top features the Asus offers that the EPoX doesn't, are these:

[*]S/PDIF-out jack for direct digital output to digital speakers or audio equipment
[*]Second 10/100 network jack onboard
[*]An additional year of warranty
[*]Better layout in some aspects (be very careful not to knock goodies off the top side of your video card with the 8RDA+'s memory clips! :Q)
[*]SerialATA controller[/list]
HTH 🙂
 
Holy Cr*p 190MHz from PC2100!:Q ,thats nuts!

Btw I just tried 157MHz CAS 2-2-2-6 & it BSOD on me🙁 (& then corrupted ZA permission file so I have to do that all over again!)

I've already ordered tha Asus A7N8X🙂 (not delux)
 
Your PC2100 may run the full-tilt 166MHz on the A7N8X. 😀 I got the impression from the A7N8X/Crucial PC2100 owners that their RAM had never run that fast stable on their non-nForce2 motherboards, you might PM SFang for his impression. The other good news, as you probably know, is that if you lock the AGP to 66MHz then the AGP and PCI busses are going to stay on spec at 66MHz and 33MHz, so you are free to pick whatever FSB/memory clock will work. No more worrying "oh no, my PCI bus is above 40MHz, my hard drive is gonna get scrambled!" 🙂
 
lol ,yeah thats why I chickened out on my mbrd at 157MHz FSB😉
Locked AGP/PCI bus, an overclockers dream come true😉

Btw I've also ordered PC2700 Crucial🙂
