GUIDE: Overclocking On EP/P35-DS3L v1.3.1 [UPDATED: 10/2/2008] - Page 8

Has anyone ever been successful in achieving a Trd value lower than 7 on the P35-DS3L board?

I managed to tweak my RAM last night to achieve a Trd value of 5!

My DDR800 RAM is running at 4-5-5-15 and DDR500 (2:50 Mem divider), FSB at 400Mhz, E2160 x8 = 3.2Ghz

Prime Stable for over 8 hours.

It took a lot of trials, it wouldn't post on many of the attempts, and I kept on thinking it was related to insufficient vMCH, but in the end it was my RAM voltage that required a hefty boost.

In the end I finished up with +0.1 vMCH, +0.1 vFSB and +0.4 vDIMM (my RAM is rated at 1.8v!!!)

Touching the NB heatsink and RAM heatspreaders, and they feel surprisingly luke warm. I expected my RAM to be burning hot at this voltage, but it wasn't so.

I have the cheap Supertalent value DDR800 2GB kit...(Silver aluminium heatspreaders).

Anyway...after performing benchmark tests with Passmark I noticed considerable improvement in Memory write times, and slight improvements in all other Memory tests.

I tried going for 4-4-4-12 timings, but just couldn;t get the thing to post...and I'm not game enough to try any more vDIMM...

Steve.

so i just started overclocking and i love it.

Computer:
Motherboard: ep35-ds3l
cpu: e2140
ram: g.skill ddr2 1066(1gx2)

so far i have been able to oc to 2.66 on stock vid and run p95 for 8 hrs+ but i cant get it past 2.66, i've tried uping the vid and fsb voltage but nothing works..sometimes it just wont start and then resets itself or it boots but when it comes time to loading the windows xp logo and loading its just a black screen and thats it...no loading of xp at all. please advise.

is it my ram? http://www.newegg.ca/Product/Produ [...] 6820231144

ps. i have set everything the way it was outlined on the first page of the thread in my F5 bios

yea the ram is set to 2.1V and SPD is set to 2 and i did try increasing MCH but didnt have much luck...the system is stable at 2.66 ghz running prime 95 for 8 hrs and i have got it to work at about 2.75 ghz but the moment i push my fsb to 350mhz i get the comp to boot but abt 3 mins into windows a blue screen comes up and the comp restarts its self.

ideally i did want it at 3.0ghz but maybe i'll have to settle for 2.66?

^What's your CPU VID?

Also did you install DES?

(Please note the problem could be RAM. There are known problems with DS3x boards and DDR2 1066 RAM).

^Yeah, it should. If you are comfortable using Q-Flash you could try the BETA BIOS and see. Also what cooler are you using?

very nice job
thanx

^That is a bit high for 2.66Ghz imo. Make sure the HSF is seated properly.

@youtube: Glad to hear that. Thank you.

^Should be in the mid 40s(45C) providing room temp is 21C(70F).

HSF= Heat sink & Fan

^If that's possible go for it.

edit:

Here is some good DDR2 800 RAM:

That RAM is able to hit DDR2 1100 with 2.2-2.3v and 5-5-5-15 timing.

Hello. I am trying to overclock my e2180 @ 2.00 GHz to a safe OC with stock cooling. Maybe 2.8-30? Is 3.2 dangerous on stock cooling?

Also my EP35-DS3L came with the F4 bios. I downloaded the F5 bios from their website. How should I go about flashing the bios? I read something about using Q-flash. I formatted a flash drive as FAT. Should I just put the autoexec, ep35ds3l, and FLASHSPI files onto the flash drive and boot up pressing whatever button it is for Q-Flash?

Also I am using one stick of this ram: http://www.newegg.com/Product/Prod [...] 6820231121
Here are pics of my bios currently:



Please let me know what the safest settings would be! Thanks

I would say read the guide, then put the max multiplier possible and start increasing the fsb by 50 maybe and do some stability and temp tests to see if its safe to keep it like that.

I've been OC'ing with the F4 bios so far and it's holding all of my changes. I decided to do 9x333 for a safe overclock. I kept the vcore the same as normal cpu vcore and got the BSOD twice while playing CSS. I
ve been slowly upping the vcore from base to about 1.4 each time it BSOD's. Is there anything else I can do?

Yes, I've done all that. I think the problem isnt the OC it's just that steam is really unstable in vista. The hl2.exe has stopped responding in vista seems to be very popular.

I have a GA-EP35-DS3L and can't manage to get it past 387fsb. I'm using an e5200 with a 2x2gb G.Skill ddr800 kit. I've tried the f6a and f5 bioses and tried voltages ranges on the ddr2, fsb, and mch in various combinations from +0.1V to +0.3V. I've tried tRD values from 3 to 25. No matter what I do, I haven't seen it post past 387. I'm able to run 3.5ghz at 333x10.5 and, if it's a cpu fsb wall, it's not that big a deal since this thing goes up to 12.5x but I would like to use 400 if possible. Any suggestions?

Hey, just got myself a new e7300 for my p35-s3l and figured I'd share my results so far.

Currently running @ 3.7ghz with an AC7 HSF. FSB 370, obviously, with 1.45v. Haven't had it long enough to do serious testing, but the blend stress test in prime went 2 hours without error. I have been able to get it up to 3.8 into windows with a 1.46v setting, but it bluescreened shortly after. I tried to go for 4ghz, but the voltage was getting past 1.5, so I backed off. It would POST, but bluescreen before even loading the user login screen. 1.43v was still causing errors in prime95, so maybe I could lower the voltage to 1.44 from 1.45, but it seems to be working fine and with the vdrop/droop, its right at 1.4v under load.

Temps are ~39 idle, ~54 full

Using the version 7 bios.

Latest stable results (10 hours prime95).

3.6ghz @ 1.435v.

using 4gb of 5-5-5-15 gskill 6400, rated for 1.8 to 1.9 volts.
Rate set at 2.3 (or 2.4 I can't remember, whichever one is the step above 2.0)

No voltages changed except for the CPU atm.

1.4 was unstable, crashed prime in 2 hours.

--
So, my question is, would overvolting a different component, perhaps the FSB, allow me to decrease the amount of voltage to my CPU, or increase the FSB speed, or would it be pointless?

Was really hoping for closer to 4ghz, but if its gonna take over 1.5v on the CPU, I don't have the balls for it.

How on earth is this guide not stickied?!?!? I hate having to go digging for it every time I need some help w/ my board.

I'm getting nearly 200ns on the 8192KB block, 512-byte stride with cpu-z latency tool (found here). TechReport is showing 55ns at stock speeds with the same processor and I've seen similar results in other places. What gives? I've tried backing down to stock and it gets even worse...

My specs and overclock info can be found in my profile.

A difference of 150ns repeated millions of times per second is sort of a big deal...

^ Did you increase RAM voltages and did you install DES?

Yes, I'll do that ASAP.

As promised:

I understand about the TRD setting mine was @ 7 but for my 800fsb to 1066 to sync with my memory i will need to raise it up abit as it crashed after 15mins and i sigh once again

I was just wondering what is the other phase adjustment setting for? as i know what the phase value does but not that one.

^Sure, go ahead and see. DO KEEP temps in check.
