3200+ Clawhammer OC results

[Adn4n]

Please post yours, I have had no success so far. I failed anything above 10x216. According to memtest I am stable at 10x230, but I fail prime instantly at any cpu voltage ranging from 1.55 to 1.65. Once, however, my system was stable in prime for 8 hours, but after a reboot it failed instantly at the same settings. I've literally tried all possible ram ratios, and lowered HT even down to 1, but still no results. According to Anandtech, I should get up to 10x230 with my SATA.

I'm getting an Antec PSU as we speak; my old one was defective. In regards to the SATA drive. Should I use SATA 1 or 2 which use the Nvidia solution, or SATA 3-6, which use the Silicon solution?

Temps:
Idle: 33C
Load:49-52C

I can speak about the 3400+, as that's what I've had for about the past year (well, one of the many boxes I have). I've got it running at 2.49GHz on Air, stock voltage, and with minimal RAM changes.

 

[Adn4n]

As mentioned above, my system was stable once at 10x230 on a 1:1 divider at 2.7v(highest). The weird thing is, I had my side intake fan turned off as I did this. The fan is usually connected to the mobo itself. I tried this again, but no luck. Not sure whether it's heat or my SATA, so can anyone post their results?

But since I passed Memtest at 10x230, it shouldn't be the memory correct? Also, did you have to change memory timings in order to pass memtest?

 

[Ronin]

Actually, the mem timings are fairly tight (2-2-6-2-1T), and I only upped the RAM voltage .1V

 

[Adn4n]

Wow that's some nice ram. Anyhow, I also tried using just one DIMM to no avail. I'm going to try 2.5 instead of 2.7 now, just to see what happens. I'll report back tomorrow. Please post your results if you have a Clawhammer.

260x10;150mhz mem multi;3x LTD;1.65V Vcore;

watercooled with GA-K8NS Pro

Temps below 32C constant idle or load and I have 2 SATA harddrives running RAID on a Promise controller.

It's tested at 265x10, but needs a lower mem multiplier... so I need new memory..

 

[Adn4n]

Does your mobo use the Nvidia solution an all 6 sata ports?

 

[stardust]

I didn't bother to find out, I had an extra controller laying around so why not put it to good use. I actually unlocked the PCI multi for a while because the controller can support up to 66mhz on the PCI bus.

In any case, it is a standard nforce3 250 chipset, so I assume it supports 2 SATA ports that are PCI locked.

The answer to your problem is that the AGP/PCI lock on the K8N-E does not work at stock settings !

You need to bump the AGP frequency up to 67Mhz (you can confirm this using Clockgen). I was able to reach 2.55 ghz with that board without any hickups. It could probably be pushed further but the bios does not support VDIMM voltages above 2.7V (unless youve got a rev. 1.05) which makes it impossible to run the memory at 1:1 eventhough the memory can keep up with such speeds.
Accidentally some of the memory speed dividers does not work either.........

The K8N is a lousy OC board so i recommend you replace it as i did (DFI Lanparty Ut Nf3 250Gb - This baby rocks).

Edit
==============================
With regards to the supposed sata issue, it does not matter which channel you attach your drives too as long as you dont use the SIL controller (its wired to the PCI bus and therefore its performance can be affected by other PCI devices).
The overclock-ability does not seem to be effect by this - i know from experience, I had 4 wd raptors connected to my old K8nE and they didnt cause any problems at all. Like is wrote above i was able to hit 2.55ghz stable with these babies attached.

 

[Adn4n]

How high do you think could I go with a 1:1 divider? And which dividers aren't working? What bios did you have? What divider did you use to reach 2,55 GHz?

Unfortunately I can't send it back, I bought it over a month ago at NewEgg.com

 

[mrupgrd]

DFI LANparty = SKT 754

3200+ = SKT 939

wish they'd hurry up and do 1 tho. they got 6 weeks then I'm gettin a K8N Neo2 Plat 54G.

COME ON DFI!!!!

Fortunately i did post those results else where so here goes.....

Fsb: 268 mhz
cpu multiplier: 9.5
Htt multipler: 3
Ram divider: 1:1 (effective speed 536 Mzh - Adata Vitesta DDR 4000)
Vcore: 1.65V
VDimm: 2.7V
Bios rev. 1.04

This worked for me.....
Note: i did manage to boot into windows with the same settings and fsb at 285 mhz, but since vdimm cant go higher than 2.7V this was unstable. This was all done on air (Thermaltake silent boost + 4 chassis fans).

I cant tell you for sure which Ram dividers does not work. I have found that this depends on the fsb.
At some speeds it doesnt work and then by bumping it up 1 or 2 mhz i suddenly works....

If you are using NVIDIA's utility to monitor speed and temps. please be aware that what you see isn't
the correct figures. If you dont have it already go get ClockGen. The NVIDIA Utitility can only be used for monitoring the temps.

The vdimm limit of 2.7V is a bottleneck for sure. As i recall it those OCZ PC3500 modules of yours requires a lot of voltage (2.8V and above) to go fast, but you should be able to reach somewhere around 2.4 Ghz providing that those modules dont bail out due to the voltage thing.

But first of all do the AGP frequency thing...without this its all futile..
After that i suggest you try and pass you previous limit. Set the fsb at something like 230 mhz (the memory will then be around its rated speed).

What are you smoking? There is a 3200+ 754, like mine, which is why it runs on my k8n-e Deluxe.

 

[Adn4n]

Ok I've tried 10x230 @1.65v on a 1:1 divider @2.7v
HTTx3
Bumped the AGP frequency to 67:


Failed prime after 3 seconds. Will try some more.

 

[ccc29249]

If you cant get it stable at 10x230, try to use a ram divider (1:2) to verify that its the memory that fails.
If you can get through a Prime test you will know for sure that the VDIMM is too low.

Check your board revision (its printed somewhere between the PCI sockets). If its a rev. 1.05 then go get bios rev. 1.05. This would allow for 2.8VDimm (this is probably still not enough, and one of the main
reasons why i dont use this board anymore).

How about the temperatures ?
Maybe your cooling is insufficient.

ok i can get 2460 stable, but ive gone down to 2400 cause with the ram devider im using it makes it a square ddr 400 again.

v core 1.7
venus 12
ht at 4 ( 1ghz ht bus )
good luck.

is yours a early clawhammer???
mine was quiet a late one, got it when the 3200 NC's had just started mixing in the retail channels.

Ehh who was that question for ... Me ?
Well actually i really dont know. Didnt bother to check since it has already exceeded my expectations considerably

 

[effee]

yea..im using a 3200+ which is a S754 on my K8V

question was for ADN 4N ( topic starter, man with the large cache )
