Can't clock Venice 3200+ to 2.4Ghz

Hi. First time OCer, read a lot of stickys!! Here's what I did:

240 HTT/FSB
10x CPU Multi
3x LDT Multi
CPU VID 1.4v (also stepped up to 1.55v - no difference)

DRAM 3.1v (also tried 3.2v - RAM is OCZ4001024ELDCGE-K PC3200 BH5 2x512mb)
Divider 1/02 (just trying to get CPU set up first)
2-2-2-8 1T (also failed at 2.5-3-3-8 1T)

Can anyone point me in right direction? Seems like 2.4 on stock air shouldn't be too much to ask for, given others running 2.5-2.6 on stock air. I know nothing's the same from OC to OC, but 2.4 shouldn't be a big deal, right?

I get errors in MEMTEST (Test #5) on 1st or 2nd pass

If I've taken FSB and RAM out of picture (didn't I with x3 LDT multi and 1/02 divider?) is it all about the CPU handling the speed? Temps are fine <45 full load (OCCT/Prime) Sometimes those run, just not MEMTEST

HELP PLEASE!! I'm not looking for a record stock air clock here am I? Just a nice little one, and I haven't done anything with RAM yet (1/02 divider????)

I am wondering about the volts to the RAM, 3.1 or 3.2 for BH5 is low (I've read 3.5 to 3.7 is preferred) but I'm still running it one a 1/02 divider so should it even matter much yet? I expected I might have to push volts to 3.5-3.7 to get RAM running faster after CPU is set up.

Thanks in advance for everyone's help!

EDIT - My sig is gone?

DFI Lanparty UT nF4 Ultra-D
Athlon A64 Venice 3200+ (E3 I believe), stock air cooling
OCZ4001024ELDCGE-K 2x512MB PC3200
Leadtek WinFast PX6600GT TDH Extreme Edition
Antec TP 2.0 550W
WD 160gb SATA 3.0gb/s (x2 no raid)

Is it possible your ram is just messed?

Also, no idea if you can with your board, but at 240, if you have some crapass PCI card, it could start failing, so you'd need to lock the PCI bus and such. But getting errors in memtest would most likely mean memory.

one more thing, not much of a reason to not keep the memory voltages up.
 
EDIT: Sorry, it's still me but under another profile. Difficult to explain but anyway . . .

I do have a PCI card (Pinnacle Video Capture) I thought the PCI bus was locked on DFI NF4 board. Do I have to do it manually?

Regarding the RAM, can't believe it's the problem, OCZ Gold BH5 is supposed to be very good. Also, regarding voltage, after 3.1volts, OCZ's lifetime warranty is voided. I really didn't want to push the RAM too much, didn't figure I'd need to for a 2.4 OC. Besides, with a 1/02 divider, can the RAM be doing anything as far as holding me back? It's set pretty slow, to isolate the processor isn't it?

Yes the PCI bus should be locked...that isn't your problem.

One thing does jump out at me right away though. That is WAY too much vdimm for even BH-5 at lower clocks. The only time you ever even need over 3 volts with BH-5 is when you're trying to run 2-2-2 timings at 230-240+ mhz. You are likely causing instability by giving it too much vdimm believe it or not.

Try this. Leave your multi at 10x...bump the HTT to 240 and run a divider to keep the memory right around 200 mhz. You can leave mem timings at 2-2-2...but this time try 2.6-2.8 volts at most. BH-5 usually will run regular PC3200 speeds @ 2-2-2 with only 2.5-2.6 vdimm....so keep that in mind.
 
Hey thanks! I am trying that now. Here's what I did:

240 HTT 10x CPU Multi = 2400 @ 1.4v
240 HTT 4x LDT = 960 x2 = 1920 HTT/FSB
240 HTT /6 x5 = 200 mhz DDR400 @ 2.7v
2-2-2-8 1T

Hmm, still getting errors in Memtest 5 or 6 passes in on test #5. Got lots of errors with same settings as above but VDIMM 2.6v

Let me try 2.8v . . .
 
Hmmm...might just have a bad stick of ram. You might try running each stick through memtest separately.

You might also try 2T vs. 1T ...worth a shot atleast.
 
Maybe on the RAM stick, I suppose.

Not too interested in 2T vs 1T. I've heard that's a huge performance hit. Wouldn't I be better off loosing the timings a little and keeping the 1T?

Also, what if I go for broke, unlock the 3.3v to 4.0v VDIMM on my DFI board, crank the VDIMM up to 3.7v or so and play around with that? Leave 240HTT and try getting 1:1 at 2-2-2-8? I've heard and read that if you feed these things volts, you can get close to DDR500?

If I was to try something like that, am I really shortening the lifespan of these sticks by running at higher volts 3.7 or so? (Assuming it works and is stable, of course) I should say that PC (and all parts) need to last me 3 years at least.

What about CPU volts? I've fiddled with it but it hasn't seemed to help too much. Is 1.4 okay? I've tried higher but not much difference I don't think. Have to check my notes.

So far so good on those above settings at 2.8v VDIMM. 14 passes and counting on MEMTEST #5. Maybe boot into windows and try some other tests now.

Thanks for your help. I'll post back tomorrow.
 
Well, so much for that. Can't boot into Windows on those settings:

240HTT 10X CPU 4x LDT 1.4v CPU
VDIMM 2.8v 5/06 divider 2-2-2-8 1T

despite MEMTEST running fine 15 passes anyway.

Any other thoughts? (2.5v VDIMM failed quickly in MEMTEST at DDR400 - I think (240/6) X 5 = 200 X2 = DDR400??? Is that right?
 
Well, so far I'm at:

240HTT CPU x10 LDT x4 CPU VID 1.55v CPU temp under 50, nF4 temp at 48
VDIMM 3.2V @ 2.5-4-4-12 1T 5/06 divider (Won't load windows under 3.2v)

Boots to windows, super PI 1M=37 seconds, 10 passes of #5 test MEMTEST
15 minutes into Prime Torture.

Guess I'll let this run the Torture test overnight, see what happens. If it passes, I'll let MEMTEST run again, much longer, try OCCT, then start 3DMarks & PCMarks, etc. I'll be shocked if I get that far though.

It's funny though, I was reviewing my notes and I was able to get 250HTT, Ram running 9/10 divider at 2-2-2-8 1T passing all kinds of tests: MEMTEST 35 times, 3DMark05, SuperPI, etc. Torture test failed in 2 minutes, after all the others looked good.

Those timings are crap though, aren't they? I don't really know. 2.5-4-4-12, at least 1T though.
 
Say, have you tried running memtest on your system at stock speeds? Just curious. I ran memtest and prime95 on my machine at stock speeds before I overclocked anything to make sure all my parts worked as advertised.
 
Hmmm, I'm having similar problems on my newcastle, I've been trying to get my xms running at ddr500 1:1, but it's a no go. As soon as I get above 214fsb at 1:1 the system becomes unstable. Have you tried another board? What is the 12v rail on your psu?
 
Yes, I've ran a battery of tests at stock speeds, 2 months ago when I first put the system together including MEMTEST (several hours, many passes), Prime Torture test for 24 hours, OCCT, 3DMark03, 05, PCMark04, Aquamarks, etc. The system is rock solid at stock speeds. I also use it for video editing AVI files, etc. Never had a problem, not once.


I ran Prime for 6 hours last night, no problems at the following:

240 HTT 10x Cpu multi 4x LDT 1.55 Cpu VID

2.5-4-4-12 1T @ 3.2volts using 5/06 divider DDR400?



Anyone use the OCZ BH5 ram and have experience with it at higher volts? What can I do (if anything) to tighten the RAM timings a bit?

How did you get your clawhammer to run a fsb so high? Is that at 1:1 ram divider? The stepping of my newcastle is a CG also and as mentioned above, it won't go past 214mhz at 1:1. Will do it using a ram divider though?
 
Have you tried running at 1:1 and loosening the timings? try 3-3-3-8-1t at 1:1 and see how far you can push the HTT at those timings

Don't have another board to try. The 12v rail is dual 12v rails, 19a each so 38a total.

PS - According to Zebo, from what I've read, using a divider (vs that 1:1) is not going to hurt your system much if the CPU Mhz is up there. His tests have shown slight increases, 1-2% or something like that. There's a great thread about it here. I don't care about running ram at 1:1 any more, just want tighter timings.
 
If the sata slot was aimed at me, I've tried both. I can run 240htt if I use a divider. Thats why I'm posting because my probs are very similar

When you run your divider, do you know what your memory speed is in windows?

1 & 2, but that shouldn't matter as all SATA ports are locked on the DFI nf4 boards.

Try 3 and 4. They aren't locked for 1 and 2 I think. That may just be your problem.

What do you mean? I think it is 240 X divider (5/6) or (9/10)

(240/6)x5=200 mhz
(240/10)x9=216 mhz

Like that? Is that what you mean?

According to Angry Games at DFI-Street, all SATA ports are locked on nf4 above 240HTT, NF3 boards were only locked above 240 HTT on ports 3&4. Not an issue on NF4.

Don't think this is my problem, but moving to 3&4 wouldn't kill me either I guess.

Yep, i was gonna say have a look at cpu z in windows, but that will do. What are the stock timings of your memory? Try stock timings and see if you can further push the fsb, I read that the venices should be pushing 2.5/2.6Ghz
