Acer Aspire 5552g Radeon 5650 overclocking

Hi
Im looking for notebook for gaming with HD5650 card and good cooling system for card overclocking. So far i found Acer 5740g and 5552g both with this card i gonna choose between them. I read whole 5740g owners lounge thread and its very informative. But this notebook is harder to get these days and its somewhat more expensive than 5552g

I read that 5552g gets about 6700 in 3dmark 06 with unclocked card
Laptop Acer 5552 5552G N830 4GB 500GB HD5650 HDMI (1304751854) - Aukcje internetowe Allegro.

so its comparable with unclocked 5740g. 5552g has somewhat thinner case so it might get hotter than 5740g.

Anyone has 5552g and got any suggestions which one is better?

 

actually i didnt spot that some 5552g hasnt got system installed, so the prices are comparable. But the 5552g has more atractive appearance for me.

 

i'll like to recommend the 5943g that i'm using

 

The phenom II probably wont do well against the core i3/i5s.

 

yes 5740g with i5 would win but its hard to get now in my country but ill keep looking for it, however i found some models with i3 but only few. This 5943g is nice but little overpriced. 5551g/5552g is easily available and it looks nicer than 5740g, but my main need is good performance, so i probably stick with 5740g

made a comparison between somewhat similar phenom x3 and i3.

Core i3 and Phenom II are comparable in real life situations (including gaming)
There's a drawback to 5551G though- it gets rather hot compared to 5740G.
Compare these temps from a German review (CPU max 91*C, GPU is HD5470 so I'll ignore it, ambient 21*C) with these from a Polish review (CPU max 95*C, HD5650 max 81*C, ambient 25*C). Mind the fact that ambient temp of 25*C is not that hot yet the CPU is very hot and the average tem of the bottom of the chassis is 42*C but parts of the bottom got up to 57*C!)

Aspire 5740G in my tests got up to 81*C on CPU and GPU got to 71*C while OCed (max 67*C on stock freqs).
Although in Polish review of 5740G they've somehow managed to get Core i5 up to 91*C (a lot more than me) the chassis still stayed at 35*C (max 48*C near the exhaust).
These new metal Aspire Timelines tend to get hotter than the old Gemstone Blue series.

 

thanks downloads. polish is actually my native language how did you know

so in 5551g gpu temp was max 81*C without OC and in 5740g 67*C without OC. thats quite a difference

Im curious if there is a big difference in gaming performance between i3 and i5 in 5740g?

 

If there's a difference between Core i3 and i5 in terms of gaming? Yes and no.
Most games don't put 100% load on CPU and in this case it's the GPU that limits your framerate co there will be no noticeable difference between the two, however some games like GTA IV, BFBC2 (if I'm not mistaken) and strategic games in general (due a lot of AI calculations) do like more CPU power an in these cases the TurboBoost of Core i5 will be a significant advantage.
If you can buy a Core i5- even the slowest one available it's probably with it but if you can't, keep in mind that it's the GPU that's the most important for gamers and Core i3 is a really good CPU.

Have you considered Aspire 5820TG?

 

You mean those from timelineX series? They are lightweight and compact but i dont care about it cause im looking for less noise and lower temps for OC

 

I can't say that for sure because Aspire 5740G owners lounge is a lot bigger than anything about 5820TG but although 5820TG gets hotter it's also easily available and looks like it overclocks better especially in memory department so it may be worth a look.

 

i dont know well its still the same card and cpu in 5820tg and it has a higher price I think ill stick with 5740g also because of the toutagamon videos on youtube which show some nice performance

 

Yeah I know something about the performance as I own 5740G. Eight months, 14 games, no problems
5820TG is not gonna be any slower though- price increase is due to metal chassis and significantly bigger battery.

 

well maybe in that case metal chassis assists in cooling cause metal is good thermal conductor isnt it?

 

That is the case but the problem is that makes the chassis hot and you would think GPU & CPU would be cooler but they won't because the notebook is thinner resulting in thinner heatsink and thus higher temps.

 

downloads, could you clarify the clocks of OCed GPU in your test? I'm about to buy a 3D notebook, but restricted in money) This stuff (i mean the 5740dg version) seems to be a good choice due to It's Rad5650, but...worring about overclocking. As i've read here http://forum.notebookreview.com/har...acer-aspire-5740-dg-hd-5650-memory-clock.html
the GPU in 5740dg has slightly DCed memory(1500 MHz effective instead of 1600). So there is only one question. Why?! TDP? It's absurdly! What if Acer installs slower memory to gpu? So it's extremely important for OC.

 

You are right- for some reason Aspire 5740G has stock freq of 750MHz for memory instead of 800MHz. It's probably connected to memory chips that were used on some units- nothing to do with TDP though.
My GPU is routinely OCed to 670/900 the memory could go a bit higher but no more than 950MHz- I wasn't really bothered to determine it exactly.
As usually some people have better results that I do and some get worse when it comes to overclocking- memory goes up to 1100MHz on some units.
See owners lounge for more details and benchmarks.

 

I don't experience any of those high temps with my laptop (5553G, (almost?) same as 5552) though.

Even with gpu clocked at 675/960 (which I'm constantly running on) GPU temp has never been above 74 degrees celsius and the cpu (despite all cores at 100% in the stresstest) has been stuck at 71 degrees (the fan kicks in full throttle at 70) (checked both aida64 and hwmonitor). Haven't had the GPU clocked higher than that yet though. CPU overclocking seems to be impossible though.
