Icee's NF7-S R+D Testing

[Charles Wirth]

Grats Opp, nice Fkin dragon low sir.

[Yitch]

Outstanding work OPP!
It's great to see a 2.9 GHz AMD competing with 4 GHz Intels.
It's a shame you've had so many problems publishing to the ORB.

Yep, and this will be even better, to bad the CPU Mhz is so low 11x237. We need 250 FSB in this mobo, we could could do 1 stick and blow doors.

Here's some NF7 and Dual Kingston Lovin

[Hallowed]

Whoa.

Even with the lower clockspeed wouldnt that FSB make up the difference?

[gokickrocks]

hows the vmod writeup for the nf7 coming along?

just wanted to check on the progress, no need to rush

[MrIcee]

The Vdd mod is 100% successful as demonstrated by OPP..and my testing is conclusive also.

The Vmem mod as I initially concieved it with the voltage regulator circuit DID NOT work as I anticipated, but I have a mod that DOES work and I'm involved in a trial period test before I make it public. There are some "possible" long term risks, this is not written in stone but as with anything it exists. The upside is it's the easist volt mod I have ever done and this method could be a Universal volt mod in cases where a pin mod on a voltage regulator is far too difficult, or in a case such as the ABIT IT7 Max2 ver.2.0...where the board is different from previous iterations and the mod from older versions doesn't work.

I don't like keeping you guys waiting, but I don't want everyone killing their boards When I'm satisfied with it on my own board you will have full disclosure

Randi

[N8]

So this "simple" mod could perhaps work on the 8RDA+ rather than having to cut a trace on the board?

For more VDIMM that is.

Great work Randi, you & OPP both have that board flyin

[MrIcee]

Yep...it's possible

Thank you for the kudo's...not sure if you've been watching my Ti4200 work...but I'm aiming for the top of that class before I go back to the Radeon. 16,6xx isn't too shabby for a Ti4200 with a 2450Mhz T-bred B on air Wait until my mod work is fully evaluated and I take a stab at the top, with my system back in the Prometeia:thumbsup:

Randi

[N8]

Now you don't think I've been watching ya?

I'd love to see ya @ the top of that class...I don't think I can get close with this CPU as it max's @ about 2420MHz on air, I'm guessin 2450 on my water...and of course I don't have a NF2...still runnin a simple ole 8K3A

Go get macci

[MrIcee]

Dang...I'm doing 2450 at 1.8v with the SLK800/Vantec Tornado combo

PS. Just did the VCore mod tonight to see how high I can go on air...then it's on to the Prommy for some serious chit

Randi

PS. It really is time for you to get an nForce 2 board Nate..LOL

[N8]

I'll tell you what. If you do in fact figure out an easy vmem mod for the 8RDA, I'll buy one

I can't buy the NF7, I need the 4 holes for my waterblock...and this KD7 I bought really is a POS

My next fear is owning a 8RDA & getting nice scores, then not being able to publish them, lol

I will give this 8K3A all I've got tho, its good for 3D up to 212FSB so far...

You know...... I thought the same thing.... Bought a second one cause I could believe the first could be that bad....

I now have 2 of them sitting on the floor in my closet..

[Firelord-OCHW]

Well wow is all I can say

Great work both Randi and Opp great to see AMD finally regaining its speed crown and on its way to ruling the roost

Tis a shame that the ORB is extremely Intel biast, it kinda smells of something.....

Once again great work and confirmed my choice for my nForce2 board

[QuadDamage]

Mr.Icee,

how far will your ti4200 go? is it air-cooled too? 16.6k isn't that bad really. i almost hit 17k, but with ti4600 and 2400+ @12x204 all air cooled, lol

[MrIcee]

Quad

I have the ABIT Siluro Ti4200 OTES 64 MB(The mem is not very good BTW for clocking, 3.6ns Hynix) clocking at 370Mhz on the core..and 670Mhz on the memory.

I am having an issue tho..and not sure if it's Ti4200 or not until I swap in the Radeon 9700 Pro:

At any FSB starting at 217Mhz and up....even with the chipset mod at 1.9v and mem at 3.1v...I get all kinds of screen flashing..or artifacts kinda like pushing your vid card memory too high. I spent all night last night trying to overcome this. I want to bench at 217-220 Mhz and I have the memory and bus speeds to do it..but something is throwing a roadblock at me.

The worst case scenario I've experienced at 217Mhz+ is the flashing culminates in a screen freeze which turns to a black screen...then after 30secs desktop items starting popping back onto the black screen...but I have no control and must reboot.

Any idea's Oh membership of wisdom???

Randi

PS. The Ti4200 is cooled with a Swiftech MCW50-T and -25c chilled coolant.

[MrIcee]

I will look into this. Are you using the Nvidia 2.0 driver set or the ones that came with your motherboard

Randi

[QuadDamage]

Mr.Icee

well, first of all your core o/c almost matches my ti4600, but mine is still air-cooled by Alpha HSF + 2T Wall A/C Unit blowing right at the whole thing. Impressive o/c

Back to the topic. I had the same issue at 207fsb / 211fsb on Asus, so as you can see i had no choice, but to bench at not too shabby 204fsb Playing around with diffrent timings combos did not help at all. I could run Sandra benches at 211fsb for hours, bit no-go for 3d fun. I thought it's prolly NB cooling unable to cope with heat, so i re-applied ASIII and made sure hsf does its job, but still same story, it was like first few seconds into Car Lo at piss poor framerate, then screen froze, back into test, artifacts, blank screen, end of the bench... i was using 2.0 nvidia drivers too. keep in mind that even video underclocking didn't fix this issue. Then i thought it's agp not getting enough of juice therefore forcing video to crap out, but crankin it up to 1.8V didn't help.

[MrIcee]

I'm on the same track as you in mentioning the 2.0 Nvidia drivers. I have never used the ones ABIT supplied..and I need to ask OPP what he is running.

I tried 1 stick of ram and the problem is FAR worse than 2.(in each Dimm slot I should add)

My avenue of exploration has been to remove the video drivers and remove the nVidia 2.0 drivers and install the ones ABIT supplies. Guess what?? They will not install off the cd...LOL Nor will they install if I browse the folder and manually run the setup.exe. I'm off to download them off Abit's site and see if I have any better luck. For everyones info...I have a Socket7 HSF on the Northbridge...and a Vantec Heatsink with an old ABIT northbridge fan attached, on the southbridge. Heat should not be an issue here...nor are available voltages. I'm hoping it's just a driver issue...but we'll see

Randi

Randi,
I've had this same issue with the fsb at around 218-220. I had to go up to 2.0Vdd to alleviate the situation.. It's a lot of voltage but it did the trick.. I'm guessing you may have already done this..if not it's worth a try.

[muzz]

Randi I know this may sound stupid, but are you running those fans off the mobo headers?

[MrIcee]

Running 1.9v on the chipset at the moment....was a tad afraid of going much higher as I toasted my last"bought" NF7-S when I first did the Vdd mod.

Muzz

The only fan running off a motherboard header is the northbridge "socket 7" fan which shouldn't be a problem. The Vantec Tornado and small ABIT fan on the southbridge run off the PSU directly.

Randi

[muzz]

Looked that way( what you said).. just checkin' mang.

[twiggy]

Something is weird. On my NF7 I was able to bench at 217 fsb and never had any tears or corruption. Then I let my bro take the mobo to try out on his 2700+(modded) and he gets hard drive corruption at 205 fsb. wtf?!?! Same RAM, same video card.

different cpu.

btw MrIcee niiiiiiccee board cooling you got there

[QuadDamage]

Mr.Icee

Hmm, i've had Asus 1.16 drivers installed before i tried 2.00 from nVidia. Same thing. well, i need new board to contunue searching for possible sulution, i'll be getting new one within few days, until then good-luck.
