$140 for a 3000+ I paid $160 for mine but its retail. are you talking oem there? I can ebay my winchester and keep my heatsink/fan. will the new SS retails come with a better heatsink/fan than the old pre SS winchesters? If mine has SS then I will crush the 2.7GHz Osirus said wouldnt happen. Of course once he gets a SS one too he may hit around 2.9GHz.
 
well im still waiting to see what you can hit now... so lets see what you can do now, before you start saying you will crush 2.7. no phun intended here, just want to see what you can get out of your current chip... you know not alll chips overclock great.

If he gets a Winchester made on the 45th week or newer, the chip will garantee 2.60GHz overclock on the average air cooling setup. Only problem is, Its literly impossible to attain such a new CPU considering week 45 was like last week lol.

But, if you start to hunt and buy from large outlets that sell old stock fast, we should start to see Strained Silicon Winchester's flood into the channel by end of the month, early next month.

EDIT: I'm really looking forwards to seeing an overclock comparison between a Week 44 and Week 45 Winchester. It will be interesting to see how much of a difference their really is with an overclock.

For those of you who already have Winchester's but really want the post week 45 ones, I would say Ebay them or sell them to a friend that isnt planning on overclocking and give him a decent deal.

90nm SS 3000+ CPUs will be the cheapest priced S939 chips to date and they should overclock like mad. Sharky Extreme has already pointed out that 3000+ chips can be found for $140US or $175 Canadian. NCIX pricematches babe!

Wow, thanks so much for the info oc master. I wanna get a 3000+ soon but then now that you've said that, maybe i should wait. Since i'm literally broke and poor, I need to save as much money as i can. Plus I just bought Half Life 2 so i need a rig to play it on soon. Can't wait till those week 45 chips come in!
:santa2:
 
There is talk that Osirus's cpu may in fact be SS because of 2.7GHz at 1.55v which no one else but the lucky few have gotten. So yea if mines SS I should also hit your clocks at around 1.6 volts or hit around 2.5GHz at 1.4 volts, something you can also do at stock volts. If mines not SS ill probably be looking at needing 1.6v to hit 2.5GHz like it took Sent. to get. Basically SS overclocks about 200MHz better(could be more as time passes) than non SS.

2.6GHz at 1.4 volts? Its official, you have a strained silcon one!

http://www.ocforums.com/showthread.php?t=343167

Its reported that many of the SS ones do 2.6GHz at stock 1.4 volts because that is 4000+ speeds. you could probably get 2.75GHz at 1.6 to 1.65v if you wanna run this high just for benching.

Is that chip on AIR or LIQUID? If your doing 2.6 @ 1.4V or less on AIR, then you're one lucky guy and most likely have one very rare cpu.


OC-Master
 
it doesnt matter, watercooling lowers the temps allowing you to use higher volts and higher clocks but 1.4v does not get hot enough to hold you back on air to begin with. He would only have problems at 1.6v and up that only water could keep the temps in check.

stock 3200+ strait run with my slower ram. gonna set it to 3000+ now then ill swap my bh5 in and see how much I gain. Once I get my winchester, I wonder if my stock 1.8GHz winchester can match my 2.2GHz newcastle using a strait stock run. my 9500np was clocked to 350/330. I will use the same ram timings on winchester as newcastle. The only variables will be dual channel and a 90nm cpu. Id like to see if the 300+ MHz gains is true, if so my 1.8GHz winchester should be equal or VERY close to my 2.2GHz newcastle ;)

heres one at stock 3000+ speeds. only gained 500 marks going to 3200+ :confused: looking at my 3200+ I might have had a bad car run but ah well, I did a strait run and did not re-run any tests. Its just a rough comparsion when I get winchester I will see how far ahead my winchester crushes my newcastle

Yes I am running on Water. I havent tried anything higher then 2.7 though. Im sure I can hit 2.75 or close to 2.8ghz with some major vcore.. You can check my thread in the AMD section for my first oc'ing results, It shows 2.5-2.6ghz on stock vcore. If I had a link I would provide it. When the wife goes to bed later tonight, Ill try for 2.75 or even 2.8 on 1.6 or 1.65 vcore.

Ill have 2 days to try and get it stable, cause Tuesday my 6800 Ultra will be here. my 480w might not be enough...

and here you go.. - http://www.ocforums.com/showthread.php?t=337403&page=1&pp=30

3000+ bh5 350/330 gpu clocks. wow it took a long time, my gpu kept crashing, it either locked, vpu recover or the monitor shut down. Had to run two tests at a time, pausing for a few min in between to let the gpu rest. Putting a huge fan over the gpu didnt help. I guess the ram artifacts caused instability and sometimes crash. 350/330 works but NOT stable! also my car low was 17fps better with bh5 over cheap ram, this means I had a bad car low run before. bh5 is NOT 400 marks faster, maybe 200. I only ran once so this does not take into account for good or bad runs, I dont got time for this and I dont care with my winchester mobo soon to arrive. I will run many times on winchester, this is only to see how much slower than winchester.
 
BH5 is only just 200 points faster if you've got a video card from the stone age.

For me, it was about 600 points faster.

Ignore the Nature, I relaxed the card just for it on the 23k run.

Your card is bottlenecking your system so heavily, that it can't feel the higher memory speed. I've noticed, though, that all Newcastles have some trouble with it.
 
so would you say going to bh5 is the equivalent of about 75MHz more cpu clocks or 30fsb more? 10fsb=25MHz cpu equivalent. I can gain 200 marks going to bh5 or upping my cpu clocks 75MHz. about 2.5 marks per MHz
 
Ok, OC550.. here are some screen shots for you...

2.4ghz on stock vcore - http://sevenlabs.net/a64/2.4.jpg
2.5ghz on stock vcore - http://sevenlabs.net/a64/2.5.jpg
2.6ghz on stock vcore - http://sevenlabs.net/a64/2.6.jpg
2.7ghz on 1.448 vcore - http://sevenlabs.net/a64/2.7.jpg
2.7ghz on 1.536 vcore - http://sevenlabs.net/a64/3000.jpg

I hope this prove's that I got a killer chip, I just might be one of the lucky one's around.

Come tuesday when I get my 6800 Ultra, Ill prime test it again, just to make sure the 6800 Ultra isnt going to make me unstable. if it does, time for a 500+watt PSU.

Very highly tuned.

Memory bus at 245 MHz 2.5-4-4-7 1T with dual channel 91% efficiency.
2.6 GHz at ~1.4 V stock, 2.7 GHz at 1.54 V.

You may want to put all your screen shot links into your post in the result collection thread.

Let's see what the 6800 Ultra will do on 3D01, 3D03, 3D05. It will further test the whole system and memory bus for stability.

You CPU is still with the older stepping CBBFD, don't know whether it is SS SOI or not, would be interesting to find out.

In a few months, when a good Nforce4 board + PCI-e video card + SS SOI Winchester/Venice all hitting the street, there will be a new level of performance standard, ....

Oh I plan to test the system highly when I get the 6800 Ultra. I might be needing a new PSU, as seeing how the Ultra requires 2 indepentent molex connectors.

Ill add my links in the thread right now.

I owe almsot all my overclocking a success to you hitechjb1... you helped me out the most :attn:
 
crazy cpu clocks but ras-cas4 is gonna hold you back pretty good. ras-cas2 at 200fsb will be considerabily faster. Some good tccd ram will help you tons if you can get 1:1 action, else try to run your ram at ras-cas3 async. anyway my 9500np is misbehaving, I dont yet know if it doesnt like the 4.11 drivers or if its messed up hardware wise :( it keeps crashing, locking or giving me a vpu recovery even at way below my max overclocks. ill see if I can give the 4.12 or 4.10s a go
 
i just noticed yur cpu sandra score, i was expecting it to be higher. mines is 11707@ 2.54ghz and I can do ddr and if my mobo was dual channel i would be getting 2x3715=7430 or higher since i can do ddr540...hahaha

well i have to find SOMEthing to comfort myself w/ my OC :D

turn vpu recover off while benchmarking.
 
With TCCD, at 245 MHz, it would run 2/2.5-3-3-10 1T, slightly better. But the memory is already running 1T, that is the important factor.

Had it be a 3200+ (a big if, if it still runs at 2.7 GHz), with x10, the memory bus would be 270 MHz, and it would be getting higher bandwidth, but that higher bus frequency and bandwdith may not necessarily be scaled linear with performance, as bandwidth once passes certain bus frequency is no longer the critical bottleneck in an A64 system.
 
so with that said hitechjb1 - is it a good idea to try and buy some TCCD based ram?

The ram I have now, is said to be using Samsung based chips.

What will the difference be honestly?
