7811FX and P9700 Processor?

Hi All! Been a while since i posted here. I've searched the Modded Bios thread, and can't seem to find an answer whether this CPU will be recognized in Bios. Does any one have a release notes or an inf file that would tell me this? This chip was released recently, sounds like a good replacement option for the stock P8400, but as these Bios's supplied through E-wrecked by Gateway were released so long ago, I don't know whether FX's BIOS will recognize. Can anyone confirm either way?

 

My advice would be to purchase it through someplace like ExcaliburPC or XPCGear and read up on their return policies. Buy it and see if it works. If not, return or exchange it for a chip that you know does.

The only fundamental difference is the chip doesn't actually have a 25W TDP, it's actually listed at 28W, which is still damned good.

I dont see why not, same die, same TDP, pretty much the same voltage range.

 

Hi Capper5016 & DestruyaX! Thanks for post! Capper, did your T9900 auto detect in Bios?

 

Yeah, without issue.

One thing you will have to do when replacing the processor in the notebook after you install the new processor is to go into the DEVICE MANAGER, select PROCESSORS, and click uni9nstall for both processors that show up (both cores of the P8400), then reboot, and the new processor will be detected.

 

That's all the info I need! Thanks and + rep!!!

 

I think it should work its pretty similar to other cpu's that came in that laptop.

 

Have you installed the P9700 yet? I'm seriously considering the same upgrade, would love to hear how it went, where you bought, etc.

 

I'm not buying the chip yet - don't want to spend the money right now. If there's one nice thing about CPUs, the price rarely goes *up* until they stop making them.

 

What is this Turbo Boost Technology that the T9700 has over the T9900? Also if you had $600 which one would you buy?

 

I would go with the cheaper of the two but go with T9600 because the cap is 3.06 and .26 isnt much for 200.00$.

 

Looks like I'm the guinea pig, then: I ordered mine yesterday from ExcaliberPC for $385.75 - they have over 200 units in stock so I don't think the price is going to drop significantly anytime very soon, tho it certainly will in the long run.

It's supposed to be delivered early next week; I'll post back with the result. I'll either have a speedier FX-7811 or a really funky looking paperweight.

 

Hey All! Sorry, been away a few days. I did end up ordering the processor, should be here Monday. It will probably be a few more days before I end up installing it, but will keep ya'll posted. Bought ICD-7 paste, hope to redo CPU, northbridge, and GPU all at the same time thanks to an excellent guide by Azrickster. At the same time, I'm going to be reformatting with XP-Pro 64 and my desktop with Server 2003, so I can get some experience in with the whole client/server thing (hoping to get some MS certifications in the near future).

 

Could you provide the link to that guide? Sure would be handy...

Thanks!

 

Link is for a 7805 teardown, but from what I've read is the same for 7811.

As all I want to do is swap out the CPU I'm assuming most of that tear down is unnecessary for me, right? Basically it sounds like remove one cover and loosen five screws, or am I missing something?

 

you have it correct for the CPU and also the Northbridge exposure........

 

FedEx says it'll be here tomorrow (Monday)... fingers crossed!

 

One of the interesting things in the 9700 over the 8xxx series is the inclusion of the "Turbo Boost" tech, which seems to be a dynamic overclocking feature meant for Nehalem. Something tells me since there's no option in the BIOS for it, P9700s in 78xx notebooks will just give 2.8Ghz: http://www.intel.com/technology/turboboost/

 

Thanks for the link! I didn't read the white paper but the article and the video both led me to believe that the TurboBoost is internal to the CPU, and does not need to be BIOS enabled. I say this because Intel is usually pretty good about outlining requirements like that, and there was just nothing said. The visuals in the demo showed no feedback loop or other input from outside of the CPU; it sounds to me like if your current, power, and temps are below maximum and the core is fully busy you get the boost until one of those conditions no longer applies. Pretty cool stuff! Or am I missing something?

 

Its sounds neat, too bad its only 133Mhz

 

Actually, the way I read it - and I could be wrong - it steps up 133Mhz numerous times until power, voltage, or temp is exceeded (or the core drops below 100% utilization). If I'm understanding it right it really is quite a sophisticated and powerful technology... the real-world benefits, who knows?

 

Yeah hard to say, the only indication I get is that it says when the OS requests the P0 step that it would kick in. And since it is only one step I assume that it only increases by 133Mhz once, who knows.

 

Intel's language is confusing, but it sounds like it ramps up in 133 chunks until some other limit is hit:

"the processor frequency will dynamically increase by 133 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number of active cores is reached"

If they said "for" instead of "on" I'd think it's just one boost that switches in and out. But it's hard to say what they really mean; if I have time later I'll look over the White Paper.

 

Hi all! Got the processor today, hope to do some work tonight on teardown, reapplication of thermal compound, and rebuild. I'll post when I'm done, maybe try to run some benchmarks.

 

I wasn't home today when FedEx tried to deliver so I won't get mine until tomorrow, but I'm right behind you! Best of luck, would LOVE to see some benchies (or helpful hints if you run into any snags)...

 

Just finished and booted up, did have to uninstall processor cores in device manager, then reboot to properly identify processor. I had real trouble with the ICD-7 TIM. Stuff is thick and hard to apply. Tried leaving tube in hot water, made it a little easier but not much. Going to run burn in software overnight to help TIM settle in. Windows aero experience went from 5.2 to 5.6! Hope to have some benchmarks for you tomorrow!

 

Don't forget you need to change your sig! Glad it went well, I'm going to be using Arctic Silver, hopefully not as hard to work with...

 

I would love actual real game before after results! Thanks in advance.

 

The only game I really play is World of Warcraft which is notoriously hard to benchmark with any kind of meaningful results; sorry.

 

DONE! And ridiculously easy, if I say so myself. The thermal pad over the Northbridge was in perfect condition so I didn't change it, the replacement went exactly as shown in the videos (THANKS Capper5016!), and probably took all of 20 minutes tops...

As for the results I couldn't be happier. The CPU has always been the (very) weak link on the 7811, not taking advantage of the DDR3 memory and not keeping up with the GPU; overall the machine now feels a LOT snappier and more responsive, and in terms of Windows Experience my score went from 5.2 to 5.6 (CPU limited).

What's really remarkable, however, is that two other WEI scores went up as well, the Graphics from 5.8 to 5.9 and the Memory from 5.7 to 5.9, so now it's 5.9 across the board except for the CPU score.

In terms of heat my fan behavior seems to be identical to what it was before, unfortunately I didn't do a before/after hardware temp test but anecdotally the new CPU seems to be just as happy in there as the old one was.

 

Did you use AS5 or ICD7?

 

AS5. It's so easy to get the heat pipe assembly out tho that I'd consider re-doing it with ICD7 if people think it really makes that much of a difference. What say?

 

Hey Tallan! Glad it went well for you. Yes, doing just the CPU is quite easy, and glad your northbridge pad was alright. Mine was broken. Azricksters guide is quite good, if you ever feel like taking it the rest of the way apart. Yes, my CPU does make the OS and apps seem snappier. My next step is a reformat with XP-Pro 64.

 

I thought about that but decided to wait for Windows 7, which should just fly on our modernized machines.

BTW Intel has a nifty little Processor ID Utility which shows a lot of the "guts" of what the P9700 is doing - look for PIDENU21 if you don't already have it.

 

@Tallan & ShortBtwnHdset,

Can you guys do a run through 3Dmark06, and then run a CPU test to see how much the CPU ramps up the frequency? It would be much appriciated

 

Many apologies but I don't do benchmarks - I just don't have the time. Hopefully Short can accommodate...

 

I'm joining the club! T9600 on its way.

 

Welcome aboard!

One thing I noted doing mine that wasn't covered in the various tear downs and videos is that the five screws that you have to loosen to remove the heat pipe assembly are numbered 1 to 5, starting with the one closest to the fan to the rear and ending with the big screw by the Northbridge. I would recommend loosening in order from 5 to 1, and tightening when re-installing from 1 to 5.

Good luck and let us hear how it works out for you!

 

T9800 seems to be the best price right now, same as the t9600and $100 cheaper then the p9700.

 

Okay, had a minute to play some WoW, max temps with the new CPU according to HWMonitor:

TZS0 = 62
TZS1 = 62
CPU1 = 56
CPU2 = 57
GPU = 70

This was after a pretty good frag fest playing with a friend, both fans were blowing as hard as I've heard them, so it seems to be well within safe limits, no?

 

Mother of god...WHY? Use Vista64 until Windows 7 Pro if XP is that important (just realize that XP Mode won't do 3D).

Using XP64 is sort of like being in Opus Dei. You have to suffer to use XP in 64-bit mode. They should call it the "Cilice Edition."

 

Hi DestuyaX! I'm currently taking network engineering, and need a client /server setup. Only have two computers right now, this is the cheapest way to go. I'll be putting 2003 server on desktop system, and XP-pro on laptop. I've used 64 bit pro before, best way I can figure to do this, Eventually, I'll put Win7 on laptop, and try server 2008 on desktop, but after I'm through learning the aformentioned.

 

It's your computer. If you've got access to WS 2003, why not use that?

 

What did you guys use to clean the CPU before applying AS5? Alcohol?

 

Ummm... errr... huh? (Just kidding.)

The sad truth is "Nuttin, honey."

I used a Bunn (the best!) coffee filter to clean the CPU and heat pipe, it really does a nice job polishing as it has a very slight abrasive quality, and after everything was shiny as new I applied the AS5. I read years ago that most isopropyl alcohol sold in America has a small amount of emollient (lanolin?) added, so as I didn't have any of the 100% pure around I bypassed any solvent/cleaner step entirely.

My temps above would seem to indicate the technique worked okay... your mileage may vary.

However if I ever have to redo the TIM on the GPU I'll definitely want, after all the work of the teardown, to go with a proper cleaner and use ICD-7; would somebody in the know post a couple of good online sources for these?

Many thanks in advance!

 

Arctic Clean is outstanding. If you need to clean it right away, grab some 90% rubbing alcohol from a drug store or super market.....or grab some denatured alcohol from home Depot.

 

Capper, what's a good source for Arctic Clean and some ICD-7?
