Which CPU to upgrade the P-7811 FX?

Hi guys,

I know about the new chipset stuff and old CPU's like x7800, x9000 can not be used on this computer. My question is as of now, either for sale or just announced, can anybody provide a list of CPUs which can be used on this lappy. P series CPU are available but the best out there is P9500. Are there any quadcores coming up anytime soon? Also other than the X9100, are there any other extreme CPUs coming to the market any tine soon?

 

Excellent questions, I'd like the answers too. And any pricing data and/or where to buy info would be outstanding as well...

 

P7350; P8400; P8600; T9400; P9500; T9600; X9100.

Quad-Cores have not been released yet, and I am not sure what type of socket they will use. If they use Socket B, the QC CPU is going to require a totally new mobo. If Socket P, it all depends upon the manufacturer, if the CPU support/compatibility is added in the BIOS or not. (Wiki says Socket P -> Q9100; QX9300, but there is no reference for it)

The T9800/P8700 should be released soon, and both CPUs should be supported by the motherboard,
but by the BIOS ? -> Depends upon Gateway !!

 

So then the question is , how much performance increase are we talking about between P9500 vs P8400. I can get one from ebay from here for $308 shipped after MS cashback. I can also sell mine for around $200 which makes it a $100 upgrade. Would it worth it?

 

Hell, I just went ahead and bought it. But still interested in other options like quadcore stuff for future upgrades.

 

Keep in mind that Yonah used the same socket as Merom, but Intel changed minute package details so even though the Merom was still listed as being the same socket, it wasn't compatible.

Unless you run apps that are multithreaded, quads really are a waste, and probably will be for quite some time. Programmers simply aren't given the time by their respective companies to write multithreaded applications (unless the applications are designed for Workstations/Servers), and most quite literally don't know how.

 

absolutely stupid question but i am a noob. do you guys not worry about your warranties with these upgrades or are the components in this laptop good enough to handle it.

 

for the normal to hardcore gamer, the P8400 that comes with the laptop is good enough to last 1-2 more years. for someone doing a lot of photoshop work or intense application work, an upgrade could help. As far as the warranty stuff goes, don't quote me on this but I'm pretty sure it will void your warranty to upgrade the processor, however I do not think you will have any problems sending it in. What I mean is, yes, your warranty will technically be voided, but will your warranty service know/care that you upgraded the processor? probably not, they will probably still honor the warranty.

 

ok that makes sense thanks. one more. does overclocking void a warranty or leave any evidence?

 

In 3-4 days I'll be able to get you guys some benchmarks with the P9500. I'll definitly undervolt it since P8400 undervolted to 0.9125, I guess I can undervolt this baby down to at least 0.9500. Sweet.

 

Do a freash install before sending it in. Also there is no sticker on gateways shich says warranty viod if removed if you want to access the CPU. I am upgrading it just for fun and I'll probably sell it later. I did it with the 6860 using x7800, x9000, t8300, t9300. None had any issues. You just need to know what you are doing.

 

i wish i had that kinda dough. ****.

 

ok, i am interested to starting to tweak stuff, would you say reading these forums and following the advice of more experienced users is sufficient knoledge?

 

IF you trade computers, you get to see all kinds of them. Just like eating all kinds of food if you are a cook or not

 

im looking to upgrade my cpu too. does anyone know if the cpu is soldered into the motherboard

 

it is not.
some guy here already upgraded his cpu to x9100

 

Ok, I got the p9500 installed and undervolted it to 1.0V. Per RMClock it is running at 32C idle and 68C after 45 minutes of orthos. 3dmark06 score at 1280x800 without any overclock is around 9500. I guess I found what I was looking for with this CPU upgrade.

 

NICE! i'm debating t9600 or x9100.

 

Both of those CPUs will draw more power and there fore will be warmer but probably you will getanother 10% CPU improvement. If you are looking for a CPU upgrade for gaming, I believe the P9500 is right at the sweet spot where you pay $150 difference to upgrade and get a %15 improvement.

 

Will a T9500/T9300 work in this laptop?

 

Technically, the chipset does support the old Santa-Rosa Platform CPUs, but the BIOS ? -> Unlikely.

 

Would putting a santa-rosa CPU in 7811 damage the CPU or the mainboard.?

 

No it won't, the GM/PM45 chipset is backward compatible with the santa rosa platform cpus (don't know about the GL40). But it depends if the BIOS would support them or not. If you have a spare lying around, you can try it out. There are a few montevina notebooks being sold, with the old santa rosa cpus as an option.

 

Right, that was the case with the asus g50. Well I already got the P9500 but an x7800 would be nice in there too, alittle bit hot tough. Anyways, thanks for the help.

 

i think e-wracked already tested a t7700 or something like that in his 7811fx, he said it worked. ask him. if that worked, t9300 t9500 x7800 and x9000 should be good.

 

I just want to let everybody know that P9500 and 7811 are just perfect. Lookat my temps on the CPU after 15 minutes of orthos with 0.975V. AWESOME!!!

 

The T7500 which is Merom, worked in the new chipset. The montevina platform seems to be backwards compatible. 1066MHz, 800MHz, 667MHz.. Per the Intel Spec Breakdown. And of course my hard effort in tearing apart a HP dv9000

 

So I assume you decided to keep the x9100. My offer is still valid by the way.

 

I appreciate it..but may have to pass.

 

Hi, Can anyone tell me what's involved to replace the CPU in the P-7811 FX Notebook ?
I'm thinking to get a
Intel Core2 Extreme Mobile X9100 3.06Ghz 6M QS on eBay
Thanks in advance

 

flip the computer over, take 5 philips head screws out (large plastic cover over the memory/cpu) and then take another 5 screws out to take the heatsink off. watch out for possible springs around the screws, as they tend to get lost in the computer if you dont look for them. also, the thermal pad over the chipset, DO NOT REMOVE THAT. Artic Silver 5 is not a viable replacement over the thermal pad as it is nowhere near thick enough to make contact with the heatsink.

 

Thanks a million for the quick respond once I'll get it I'll get to it

 

It would be interesting to see some synthetic CPU specific benchmark on the P9500 vs stock CPU as its not a straight apples to apples comparision in that you are doubling the L2, increasing the clocked frequency yet keeping the FSB the same.

Greater L2 cache = less RAM fetches required, no integrated memory controller in addition to the higher latency of DD3 compared to DDR2 means memory fetches are pretty high latency so this is a big +

Increased clocked frequency = greater number of Instructions per second if the CPU and be supplied with data fast enough.

Same frequency FSB = same latency and bandwidth to RAM yet a more data hungry CPU due to higher core clocked frequency. Offset by larger L2...

I would expect given the doubling of the L2 yet only a modest increase in core frequency that the performance increase would be slightly higher than a straight comparison of core frequencies. This would be offset to some degree however by the RAM latencies and bandwidth available remaining the same.

Clock per clock you would expect a ~12% increase (dependent on the benchmark and it's reliance on system sub components) yet I would suspect due to the larger L2 you would see closer to ~15% in average as previously mentioned by people.

As lower latency DDR3 SODIMMs become available these might be considered for a small performance increase also (as long the the BIOS supports the lower CAS, RAS etc) - especially with higher clocking CPUs.

 

I put a x9000 in it and it was around 10% better than the P9500. and P9500 was around 20% better than the P8400. These percentages are based on the 3dmark06 cpu score.

 

Given your results I would say the p9500 is probably the most suitable upgrade for the majority of users unless you are completely agnostic regarding battery life and heat on your rig then.

 

i wouldn't go concluding stuff based on 3dmark scores. not even as to a unit graphic abilities not to mention its cpu strength. if you look at "professional" benchmarks you'll see they never settle for one suit. cpus have grown too capable to be measured with one tool, and there are even more parameters when it comes to notebooks where heat and power is a real issue.

no facts stated.

 

Your going to love it, I got the same chip from ebay also

 

The same seller says he can get QX9300 for $745

 

would be great to know if it will work in our machines the Qx9300 that is.

is nmicro the go to guy on ebay that people have been using ?.

 

I say go ahead and get the QX9300 if you can. Worse case is it doesnt work and you turn around and sell it in a week when the computers that can use it come out and the demand is even higher for the thing.

Probably turn a nice profit as well

 

Its tempting KM but if i were to buy it id rather it go in my machine then having to turn around and sell it. This is one of the reasons i have been holding off on buying a new CPU as id rather wait abit longer and see if the quads work first then decide. not to mention last time i sold my machine all the upgrades i put into it i didnt charge my friend for ie t9300 and WUXGA screen . So after taking a 1k bath i think ill try and be patient and see what happens cause ive been spending to much as of late .

 

I know what you mean. I hate when new tech comes out. I'm itching to sell my stuff grab a 7811 and QX CPU and profit...but then i realize the 6860 does everything i want currently and i really dont need to buy a new laptop + upgrades every 6 freaking months

[looks toward the mid 2010 horizon with great anticipation]

Well if you dont buy it i hope someone does, i would like to know it works and how far you can clock it using the crippled gateway BIOS (if you could get 3.0 then that would be a MAJOR upgrade to the machine...talking desktop power)

 

Looks like alitunay is now on ebay selling 7911's with the x9100...Just go to ebay and type in x9100 under search and his will be the only laptop that shows up...

Also, What is a good price to pay for the x9100 because their is only one person so far that I have seen selling it and thats on ebay for 485.00

 

looking to do this upgrade on my 7811. been doing a lot of reasearch and realize this forum is a little old. looking to upgrade to the t9600 and was curious if anyone else has made this specific upgrade and if so, any issues they ran into. thanks a bunch in advance

 

I'd just ramp up to the x9100 if you can afford it. Its only 360 ish on ebay.

For several reasons, not clock speed alone, its a better cpu and will perform another 10% better...I'd say it will future proof your lappy for another year or year and a half

You'll see quad this and quad that over the next 12 months in laptops...doesn't enhance for gamers. Most software isn't even written to use 4 threads.

 

how about the T9900 SLGEE? im not sure how it currently rates as being the best but thats what i bought last week and put in my 7805u. it was 500 bucks, not sure if it was really worth it. can someone advise? thanks in advance...

 

T9900s are at the moment best processors for p7811/05/01 FX

I bought a X9100 for my P7801 FX but i can't overclock it.

So what do you prefer ?
X9100: A 3.06Ghz with unlocked multiplier (but bios does not allow to change them) without IDA with 44W TDP
or
T9900: A 3.06Ghz with IDA (3.2Ghz single core) with 35W TDP

With CPUMark99, My X9100 scores 441.
It will be nice to have CPUMark99 scores of T9900 but i think it's something like 455 due to IDA ability.

 

Hello guys, I've been following your discussion with great interest. So here is my question: due to location I can only buy one of 2 choices, P9500 or T9600.

Which one would you recommend (seriously)?

 

Get the [email protected] if it's cheaper.

 

Well I've found this thread http://forum.notebookreview.com/showthread.php?t=423866
So I'll check if I can get the T9900 as well. That would be a better choice, right?
