Re: E8300 + GA-EX38-DS4 OCing

Please give me a link to your ram and tell me how much of it you have installed.

Then I can best advise you. C1E and EIST Should be disabled for sure

Problems with Q9450? What issues did you have? Wow, I have never heard of E8300

Re: E8300 + GA-EX38-DS4 OCing

Here you go: Patriot Memory - Products

C1E and EIST off. Gotcha!

Yes, the Q9450 was the source of my OCing woes before. Not to mention that it was also the source of my BSODs and RSODs too.

The E8300 is a dual-core CPU. I suppose you could say it's the dual-core counterpart to the Q9550 (minus 2 cores, they seem to be the same). Haven't had problems with it, and hopefully I never will.

*sigh* Sorry. Got 2x2GB.

Been upping the E8300 by 10mhz. Currently at 3Ghz (353x8.5). Temps, for once, are decent (given Australia's summer weather): low/mid 50s when under load. Low/mid 40s otherwise.

Re: E8300 + GA-EX38-DS4 OCing

Well for 2x2 you should set your voltages as I noted above. Also, you can use 2.40B multi for 850Mhz for the above speed if you like. Those are 444-12 @ 800 sticks, so at 555 timings you can easily do 900-1000 once you set your voltages

Good luck, looking good so far. I have three pages of posts to get to so I will catch up with ya later

**Nova Phoenix** · 01-08-2009, 12:46 AM

Re: E8300 + GA-EX38-DS4 OCing

Thanks man.

Speaking of the RAM, a review I read did major testing of my chips and others. The Patriots, shockingly, could do DDR2-1200mhz with 7-7-7-11, and DDR2-800mhz with 4-4-4-4, both at 2.2v. But whether my particular pair can do this is not known...yet.

You think my E8300 would be okay if I upped the 10mhz boost to say 20Mhz?

**Lsdmeasap** · 01-08-2009, 01:45 AM

Re: E8300 + GA-EX38-DS4 OCing

Ya, with high/loose timings most all will do 1200 with 2.15-2.2.

Ya, I think your CPU can do 4Ghz likely. I use a E3110 (Same as E8400) and mine will do 4.4+, I see tons of E8400's doing 4.5+ all day long

So you can for sure go higher, just keep your ram loose until you are done with your CPU. And you may want to use the D strap after 400 FSB

The very advice of a mate I speak to on WLM. Overclock one component at a time. That's why the memory timings are still all set to Auto. Once I'm happy with the E8300's max potential overclock, I'll move onto the memory, and then onto my HD3870X2 (via Rivatuner).

I'm using the 2.00D strap now mate. It's underclocking the memory too, which is a good thing I guess, because I know it won't be the memory that stuffs up. If I try for 1200mhz and 7-7-7-11, I'll have to change though. Going 1:1 for that memory speed would mean a 600mhz FSB. Sounds risky to me!

Currently at posting time, the E8300 is at 3.17Ghz (373x8.5) on stock Vcore (well, "Normal" Vcore setting w/LLC still on Auto).

Just quickly, lsdmeasap, what would be more performing: 1200mhz w/7-7-7-11, or 800mhz w/4-4-4-4?

**Nova Phoenix** · 01-08-2009, 06:17 PM

Re: E8300 + GA-EX38-DS4 OCing

Update
Got the E8300 to 3.4ghz on stock Vcore (memory is still loose). Tested with Orthos, but one core failed in less than a minute (weird). Went back to Bios, raised Vcore by one increment, and I also adjusted the other voltages too (should have in the first place).
Temp wise, it's pretty good today, as my area of Oz has a nice cool breeze. Last time I checked with RealTemp, the core temps were in the mid-high 30s! :D

Update #2
Was doing some Orthos tests but they failed kinda quick. Funnily enough, after setting the NB voltage to what lsdmeasap recommended, Orthos didn't fail and went to the 15 min mark.
Decided to test 410mhz (3.48ghz) too. Went to benchmark Far Cry 2 but it caused a BSOD just as the benchmark was going to start. I kind of took this as a sign not to go any further (at least for the time being). I mean, I don't want another CPU going ass up! The E8300 is doing well anyways, at 3.4Ghz, and the 2x2GB memory at 800mhz and 4-4-4-12-2T.

Re: E8300 + GA-EX38-DS4 OCing

Update #3
I found I had to use +0.35v DIMM voltage to get the memory to 2.2v. At +0.30v, it was around 2.160v.

**Lsdmeasap** · 01-11-2009, 02:00 AM

Re: E8300 + GA-EX38-DS4 OCing

2.2V is not needed on ram, it would only be your warrantied max allowed. I suggest if you plan to keep using 2.2V you have a fan directly on the ram.

Looks good as far as settings go settings go

I am not sure how good 1200 would be at 777 compared to 800/444. I can tell you 777-7 and 444-4 will fail. tRAS should always be this >>> tRCD+CAS+2=tRAS

You will likely have issues getting 2x2 to go to 1200, maybe with 666-20 or 777-20 but it would likely perform badly. High ram speeds like that are best done with 2x1 or 4x1, I just was doing some testing at 1220 with 2x1 at 555-15

**Nova Phoenix** · 01-11-2009, 02:13 AM

Re: E8300 + GA-EX38-DS4 OCing

Okay, will adjust DIMM OV a bit later.

I have a theory why stock voltage wasn't doing too well with 3.4Ghz (was causing Orthos stoppage and a BSOD): loadline calibration.

When I was OCing before, LLC was on Auto. When I approached 3.4Ghz, I disabled it. I figured that setting it slightly higher than stock Vcore in the BIOS would equal what it would be, if set to stock Vcore and LLC on Auto.

**Lsdmeasap** · 01-11-2009, 02:06 PM

Re: E8300 + GA-EX38-DS4 OCing

You can just set voltage higher if your vcore is dropping to far, that would be better then LLC enabled. Should be disabled I think on 45NM CPU, but it is all up to you, there is many discussions about this for sure

Ram voltage, ya that would be a issue if not set manually

**Nova Phoenix** · 01-11-2009, 11:53 PM

Re: E8300 + GA-EX38-DS4 OCing

Thanks. LLC remains disabled. I read an article recently advising this. I did this on the Q9450 too - not that it did any good.

All is running well now. Temps will probably climb a bit due to the Summer weather in Australia, but I don't seem them reaching 60 anytime soon. :D

Finallly, it seems my system's lost glory is restored! :)
