E6300/DS3/G.SKILL/Tuniq

[Cheex]

Another point of concern....

My NB is still being passively cooled. There has been no additional voltage applied to it. Aside from CPU and memory voltages, how do I know when to increase the others such as MCH, FSB, etc.

What temperature should I keep the NB below?

 

[PuffDaMagicSamus]

CoreTemp and TAT read temps in the same way so either of those two should be fine. I use CoreTemp myself but I also have TAT installed and use it from time to time.

 

[Cheex]

What is the temp limit for the NB on a DS3?

 

[Shimmishim]

1. no software monitoring program will give you "accurate" temperatures. if you want an "accurate" temperature then you need to get some sort of thermometer or diode that is located very near the core of the chip or close to the NB chip.

2. passive cooling is fine. just put a fan over the NB cooler.

3. if you want to go higher, then just start upping the vcore but watch your cpu temp. keep it under "70" according to speedfan, TAT, whatever you use.

 

[Cheex]

1. Agreed.

2. Just as how you should keep the CPU temp below 70C, what do I keep the NB below????

3. I understand vCore but what about the other voltage settings, what do I increase and when????

 

[Cheex]

Another concern...I just came home and I realize that I have a cold boot issue.

What causes that and how do I fix it?

 

[Cheex]

Can anyone help me out please?

 

[myocardia]

Cold boot problems are one of the things that sometimes accompanies overclocks. As a matter of fact, some boards have cold boot problems, even when not overclocking. Occasionally, it helps to raise the startup vcore, if your motherboard has that option; most don't.

 

[Cheex]

Oh. I guess mine doesn't have that because I have never seen it in the bios. What about the other voltage settings:

What are these and what is the purpose and/or benefits of raising the following voltages:
1) PCIe
2) FSB
3) MCH

Raising those voltages, except the PCIe, can help you attain a higher overclock. Usually, raising both the FSB and MCH voltages will help, especially with lower multiplier chips, like yours. Of course, if your processor just needs more vcore, then raising those voltages won't help any.

 

[Cheex]

1.4V isn't enough to make me stable at 3.2GHz (458x7). So, instead of going higher with the vCore, would you advise that I up both the FSB and the MCH by .1V?

 

[myocardia]

Why are you running at 458? You have a 9x multiplier, and that isn't an Athlon 64. C2D's need to run at their max multiplier. See how much voltage it requires to run at 9x350, or 9x355.

at your voltage, yup... that sounds about right.

Concidering at 1.45V a tuniq will idle in thie 40's while my water idle's in the high 20's


heh... Just wait til i slap my bowed GTX tho.

I'm not running an E4300. I have an E6300.

 

[Cheex]

1.45V vCore
2.20V vDimm

I seem stable in Windows but this is still failing Orthos in like 10 minutes.
Any advice on how I can get higher than 3.15GHz?

Haha, I forgot. Anyway, you're most likely at the limit of your RAM. Try raising the timings to 5-6-6-18, and see if it lasts longer. If it doesn't, your cpu needs more voltage.

 

[Cheex]

I'm back to 3.15GHz. I haven't tried myocardia's suggestion yet but I dropped the vCore to 3.750V and tightened the timings to 4-4-4-12. Should I test these settings here for stability before I move on or just try to go as high as I can (at the current settings: 1.4V & 5-5-5-15) then do the final tweaking?

 

[Cheex]

I tried myocardia's settings now and @ 1.45V and 2.2V (5-6-6-18)...

I ran Orthos error free for 32 minutes and then stopped it. Good sign...except that...
The temps peaked at 62C.

Any thoughts?

That works for me. The only problem though, is that you'll most likely lose a bit of that overclock, once you add a second stick of RAM. BTW, if that's where you plan on leaving it, you should run Orthos for much longer. Don't worry about the temps, because Orthos stresses your processor much more than anything else you'll ever run. You'll most likely have temps in the lower 50's while gaming, for instance, and lower on single-threaded games.

 

[Cheex]

3.311GHz (473x7) wasn't stable either. I have decided to go with my original plan of staying at 3.15GHz (450x7) for now and try to reduce voltages and tighten timings while maintaining stability. I'm going to leave for work in a little while so I will be running OCCT (1/2 hour) now before I leave and if that passes I will leave Orthos to run during the day.

Settings:
vCore - 1.375V
vDimm - 2.1V (stock 2.0V-2.1V)
PCIe - stock
FSB - stock
MCH - stock

3.15GHz (450x7)
DDR2-900 @ 4-4-4-12 (stock 4-4-3-5)

From an earlier post in this thread: "40-42C can't be right"

Why can't that be right? That's a normal temp for a CPU.

Not with a Tuniq Tower 120!!

 

[Zardnok]

I think you are right at the point where you need to find out if your problem is the limitations in RAM or CPU. You know that the system is stable at 3.15. Try lowering your multi on the CPU down to 6 and then increase the speed to see where the memory tops out. 6X475 is 2850 and you know your CPU will handle that speed. If the Orthos blend fails there, you know the RAM is the problem. If it passes, you have reached CPU limitations or perhaps your Northbridge needs better cooling to go higher.

Once you know where the memory tops out, you can decide to either relax timings to try for more speed or stick with what you have.

 

[Cheex]

Here it is...

The best stable setting that I have is at 3.15GHz (450x7). I tried Zardnok's suggestion and came up empty-handed.

I got errors at even 1.39375V on the vCore (have to keep it at 1.4V) and the memory at 5-5-5-15 on 2.2V is good.

It is now official: my memory is my limiting factor.

 

[Cheex]

I don't think it is necessary to buy DDR2-1000 memory since as I have this already...but...


1) Should I just go ahead and buy my other 1GB stick and be happy.

OR

2) Do #1 and change my CPU in about May to an E6400 (2MB) or E6420 (4MB) with the 8x multiplier. With my "DDR2-900" memory, I could go as high as 3.6GHz (450x8)...although I think the CPU would max out before then (but that is okay, better than some other component holding back your CPU).
